Working past 500–Internal server error

So you’ve written a new ASP.Net website, tested it locally in your development environment and you deploy it to your IIS server.  Now you’re getting the dreaded 500 – Internal server error.  What are you to do?

image

As you may know, a HTTP 500 error is a generic error message returned by a web server when it knows something has gone wrong but it is unable to be more specific about the error.  That’s not necessarily helpful, though, when you are trying to figure out what is causing the error so you can fix it and get your web site to load.  Here are a few tips to help you find the real error so you can get your site loading properly.

If you are running Classic ASP on IIS 7 or IIS 8, just about any error that you get from an out-of-the-box installation will be a 500 error.  You should check out this blog post for more information on developing Classic ASP applications in IIS 7 or later.

  1. Run the site directly on the server – depending on the configuration of your site/server, you may be able to see the real error if you load the site from a browser located on the same server.  You may need to turn off ‘show friendly http errors.’
  2. Temporarily add the following within the appropriate tags in your web.config file:
  3. After you have added those, load the page again to see if you can get a more detailed error. 

  4. Open up IIS Manager and try to open up some of the different features by clicking on the icon.  If there is an error in the web.config file and it can’t even parse it, sometimes you will get a helpful error in IIS Manager when you try to open a feature.
  5. Look in Event Viewer.  Sometimes you can find the detailed error logged in there, particularly Application Event Viewer.
  6. Setup Failed Request Tracing.  This will often give you details on the 500 error.  This is especially helpful if it is an intermittent 500 error.
  7. Look through the web log files.   This is especially helpful for an intermittent 500 error.  You can often parse the log files to see if there is a trend with a specific page that is throwing a 500 error.

This list isn’t meant to provide a comprehensive repository of ways you can find the real error behind a 500 Internal Server Error, rather a guide of ideas to help get you started.  I will continue to update this post as I come across more scenarios.

How to Troubleshoot IIS 500 Error for ASP Websites

You try to load your classic ASP (Active Server Pages) website and all you can see in your browser is the all too familiar display of 500 Internal Server Error.

This page isn't working WEBSITE is currently unable to handle this request HTTP ERROR 500

IIS HTTP Error 500 Display on Chrome browser

What is 500 Internal Server Error

First of all, the 500 Internal Server Error is a very general HTTP status code that indicates something has gone wrong on the web server without any specifics on the exact problem.

This instruction is limited to solving a 500 error on IIS server for classic ASP websites, however some other instructions that’s related to IIS in general will help for troubleshooting IIS server for .NET applications as well.

As 500 Server Error message is very often vague, the task now is to find a more specific error message that will help us further analyze and troubleshoot the issue.

Enable Debugging and Send Errors to Browser

If the website is not in a production environment, the easiest way to do it is to enable the ASP Debugging Properties and send the errors to the browser by following these steps:

  1. Launch Internet Information Services (IIS) Manager and on the left pane, select your ASP website and click on the ASP icon (Configure properties for ASP applications).

    IIS settings to configure properties for ASP applications

  2. Under the ASP window, expand the Debugging Properties and set Enable Client-side Debugging, Enable Server-side Debugging, and Send Errors To Browser to True and click Apply.

    IIS ASP Debugging Properties settings to browser

Now, when you refresh your ASP website, you will see a more descriptive error message on your browser such as the following example:

System.Xml error '80131509' There is an error in the XML document. /itnota/failed-page.asp, line 289

ASP 500 Error detailed failed page

With this information, you can right away open the file (e.g., itnota/failed-page.asp) and check line number 289. Again, this option is not recommended for a production website that’s still actively used and available for public since it exposes too much information publicly. The ideal way to do it is to replicate your production environment on a staging and try to reproduce the error on a lower environment.

Check IIS Log

Another way to check 500 Internal Server Error for your ASP website is by viewing IIS error logs. This is especially true if your ASP website is a public website.

Where to find the IIS Logs?

By default, the log for your website is stored on %SystemDrive%\inetpub\logs\LogFile, but you should not use this settings for a production environment. Always set a custom path for your logs so your websites are easier to maintain in the long run. If you have a different physical hard drive for logs, even better. Make sure it’s set to Enabled.

IIS Log properties

For the sake of example, the log files are located in folder D:\Logs\ITNota.com:

From the IIS log example below, the easiest way is to look for a pipe character (“

PHP 500 internal server error in IIS – Causes and Fixes

500 internal server error clearly indicates that something went wrong during the display of PHP page.

By default, web servers like IIS return only generic error messages in websites. Often, this causes the masking of real reason for IIS PHP errors such as 500 internal server error.

That’s why, we frequently get request from Windows server owners to find out the reason for PHP website errors and fix them as part of our Server Management Services.

Today, we’ll take a look on how Bobcares’ Engineers track the real reason and fix php 500 internal server error in IIS.

 

What causes PHP 500 internal server error in IIS

Basically, 500 Internal Server Error is IIS web server’s way of saying, “Something has gone wrong when I tried to display the page. Not sure what.

Now, its time to see the exact reasons for the 500 errors.

 

1. Permissions Error

From our experience in managing servers, our Windows Experts often see PHP 500 internal server errors due to wrong permissions and ownership on website files. In Windows servers, every file and every folder has its own set of permissions. Again, some permissions are inherited from the parent folders too. And, when the PHP binary do not have enough permissions to execute the scripts, it can result in 500 internal server error.

Similarly, ownership of the files also create problems. In Windows, specific users like IIS User, IIS WP User, etc. should have access on the website folders and files. For example, the IUSR account should have modify permissions on php scripts. And, when there are permission problems, website shows PHP errors.

 

2. Bad PHP Settings

Yet another reason for PHP internal server error is bad PHP settings. The PHP settings are specified in the configuration file at C:\PHP\PHP.ini. PHP binary take the values from this file while executing scripts.

A classic example will be PHP timeout settings. When the website PHP scripts has to fetch results from external resources, PHP timeout values often cause trouble.  Most system administrators set timeout values in PHP to avoid abuse of the server resources. And, if the PHP script executes for a time longer than the threshold limits, it eventually results in 500 error.

 

3. PHP module errors

A very few 500 errors happen when the PHP module on the server as such becomes corrupt too. As a result, it results in processing failure of PHP scripts.

Luckily, when the website reports the 500 error due to module failures, IIS often show a more specific error messages like:

 

How we fixed PHP 500 internal server error in IIS

Fixing PHP 500 internal server error in IIS need a series of steps. Let’s now see how our Dedicated Engineers fixed it for one of our customers and made PHP scripts running.

The customer reported 500 internal server error on WordPress website running in IIS.

 

1. Turning On Display errors

While the error correctly suggested that PHP had caused 500 error code, it did not provide application-specific information about what caused the error. Therefore, the the first step of investigation was to turn ON display errors option. For this, our Dedicated Engineers followed the steps below.

  1. Using Windows® Explorer, browse to C:\PHP and open the Php.ini file in the PHP installation directory.
  2. Edit and set the display_errors = On directive.
  3. Save the file.
  4. Reset IIS using the command iisreset.exe

After turning on the errors, we reloaded the PHP and it showed a PHP parse error:

Often browser settings only show friendly error messages. In such cases, we recommend customer to turn it Off. For example, in Internet Explorer Go to Tools, Internet Options, Advanced tab, and then clear the Show friendly HTTP error messages check box.

Thus, it was a coding error on the PHP script. We suggested script modifications to customer and that fixed the error.

 

2. Running PHP script locally

Yet another way to find the exact error is to run the problem php script within the server. For this, our Support Engineers connect to the server via rdesktop and execute php script using the php.exe binary. It would show the  DLL’s that are having conflicts and causing the 500 error. We fix these conflicts and make the script working again.

 

3. Correcting PHP settings

In some cases, we need to correct the PHP settings to get the problem solved. Recently, when a customer reported problems with his website, we had to set the php directive open_basedir correctly to solve 500 Internal Server Error.

Similarly, when PHP cgi scripts show up some warning, IIS7 still displays an HTTP 500 error message. Although the best method is to fix the PHP scripts, often changing the default error handling for FastCGI in IIS7 to “IgnoreAndReturn200” also work as a temporary fix. The exact settings will look as shown.

 

4. Fixing PHP binary

In some rare cases, the fix may involve complete rebuilding of PHP binary on the server. This happens mainly when the PHP program on the server becomes corrupt. However, in such cases our Dedicated Engineers always check the dependency of the package and do the reinstall. For control panel specific servers, we set the appropriate binary on the server.

[Broken PHP scripts causing big problems? Our IIS experts have the fix for you.]

 

Conclusion

In a nutshell, PHP 500 internal server error in IIS happens mainly due to reasons like buggy PHP scripts, wrong server settings and many more. Today, we saw the top reasons for the error and how our Support Engineers fix it for customers.

Warning 9009 is an IIS error of the Application Host. It occurs when the Application Host failed to delete the history directory. The Application Host Helper Service detects any changes in the ApplicationHost.config file and creates a backup in a subdirectory. However, the maximum number of subdirectories is 10. If this number is exceeded, the oldest one is usually deleted. If this process fails, error 9009 occurs.

To solve this problem, stop and restart the Application Host Helper Service (AppHostSyc). The AppHostSyc will then start the service and delete the subdirectory automatically. If it still fails to delete the history directory, try restarting the service manually.

More information

For any exception thrown from the web application code, check Application net speakerphone socket error log or your own Application log, for Exception Type, Exception Message, and Exception Call Stack. If further debugging is needed, 500 server error iis, use DebugDiag latest version to capture first chance exception dumps.

500 Internal Server Error

The 500 Internal Server Error is a very general HTTP status code that means something has gone wrong on the website's server, but the server could not be more specific on what the exact problem is.

Are You the Web Manager? See Fixing 500 Internal Server Error Problems on Your Own Site towards the bottom of the page for some better advice if you're seeing the error on one or more of your pages.

How You Might See a 500 500 server error iis

The error message might be seen in many ways because each website is allowed to customize the message.

Here are several common ways that you might see the HTTP 500 error:

  • 500 Internal Server Error
  • HTTP 500 - Internal Server Error
  • Temporary Error (500)
  • Internal Server Error
  • HTTP 500 Internal Error
  • 500 Error
  • HTTP Error 500
  • 500. That's an error

Since a 500 Internal Server Error is generated by the website you're visiting, you could see one in any browser in anyoperating system, even on your smartphone.

Most of the time, it displays inside the browser window, just as web pages do.

Cause of HTTP 500 Errors

Like we mentioned above, Internal Server Error messages indicate that something, in general, is wrong.

Most of the time, "wrong" means an issue with the page or site's programming, but there's certainly a chance that the problem is on your end, something we'll investigate below.

More specific information about the cause of a particular HTTP 500 error is often provided when it occurs on a server using Microsoft IIS software. Look for numbers after 500, as in HTTP Error 500.19 - Internal Server Error, which means Configuration data is invalid.

How to Fix the 500 Internal Server Error

Like we alluded to above, the 500 Internal Server Error is a server-side error, meaning the problem probably isn't with your computer or internet connection but instead with the website's server.

While not probable, there may be something wrong on your end, in which case we'll look at some things you can try:

  1. Reload the web page. You can do that by selecting the refresh/reload button, pressing F5 or Ctrl+R, or trying the URL again from the address bar.

    Even if the 500 Internal Server Error is a problem on the webserver, the issue might be temporary. Trying the page again will often be successful.

    If the message appears during the checkout process at an online merchant, be aware that duplicate attempts to checkout may end up creating multiple orders— and multiple charges! Most merchants have automatic protections from these kinds of actions, but it's still something to keep in mind.

  2. Clear your browser's cache. If there's a problem with the cached version of the page you're viewing, it could be causing HTTP 500 issues.

    Caching issues do not often cause internal Server Errors, but we have, on occasion, seen the error go away after clearing the cache. It's such an easy and harmless thing to try, so don't skip it.

  3. Delete your browser's cookies. You can correct some 500 Internal Server Error issues by deleting the cookies associated with the site on which you're getting the error.

    After removing the cookie(s), restart the browser and try again.

  4. Troubleshoot as a 504 Gateway Timeout error instead. It's not very common, but some servers produce a 500 Internal Server Error when in reality, 504 Gateway Timeout is a more appropriate message based on the cause of the problem.

  5. Contacting the website is another option, 500 server error iis. There's a good chance that the site's administrators already know about the 500 error, but if you suspect they don't, letting them know helps both you and them (and everyone else).

    Most sites have support-based social network accounts, and a few even have email and telephone numbers.

    If it looks like the site is down entirely and you can't find a way to report the 500 Internal Server Error message to the website, it might help your sanity to keep up with the outage on Twitter. You can usually search for #websitedown on Twitter, as in #gmaildown or #facebookdown.

  6. Come back later. Unfortunately, at this point, the 500 Internal Server Error is no doubt a problem outside of your control that will eventually get fixed by someone else.

If the 500 Internal Server Error message appears at checkout during an online purchase, 500 server error iis, it might help to realize that sales are probably being disrupted—usually a great incentive to the online store to fix the issue very quickly!

Even if you're getting the 500 error on a site that doesn't sell anything, like YouTube or Twitter, as long as you've let them know about the problem, or at least tried, there's little more you can do than wait it out.

Fixing 500 Internal Server Error Problems on Your Own Site

A 500 Internal Server Error on your website requires an entirely different course of action. As we mentioned above, most 500 errors are server-side errors, 500 server error iis, meaning it's likely your problem to fix if it's your website.

There are lots of reasons why your site might be serving a 500 Error to your users, but these are the most common:

  • A Permissions Error. In most cases, a 500 Internal Server Error is due to an incorrect permission on one or more files or folders. In most of those cases, an incorrect permission on a PHP and CGI script is to blame. These should usually be set at 0755 (-rwxr-xr-x).
  • A PHP Timeout. If your script connects to external resources and those resources timeout, an HTTP 500 error can occur. Timeout rules, or better error handling in your script, should help if this is the cause of the 500 error.
  • A Coding Error in .htaccess. While not as common, be sure to check that your site's .htaccess file is properly structured.

If you're running WordPress, Joomla, or another content management or CMS system, be sure to search their support centers for more specific help troubleshooting a 500 Internal Server Error.

If you're not using an off-the-shelf content management tool, your web hosting provider, like InMotion, Dreamhost, IONOS (1&1), 500 server error iis, etc., probably has some 500 Error help that might be more specific to your situation.

More Ways You Might See an Internal Server Error

When Google services, like Gmail, are experiencing the error, they often report a Temporary Error (500), or simply 500.

When Windows Update is involved, it appears as a WU_E_PT_HTTP_STATUS_SERVER_ERROR message or 0x8024401F error.

If the website that reports the 500 error is running Microsoft IIS, you might get a more specific error message:

    PHP 500 internal server error in IIS – Causes and Fixes

    500 internal server error clearly indicates that something went wrong during the display of PHP page.

    By default, web servers like IIS return only generic error messages in websites. Often, this causes the masking of real reason for IIS PHP errors such as 500 internal server error.

    That’s why, we frequently get request from Windows server owners to find out the reason for PHP website errors and fix them as part of our Server Management Services.

    Today, we’ll take a look on how Bobcares’ Engineers track the real reason and fix php 500 internal server error in IIS.

     

    What causes PHP 500 internal server error in IIS

    Basically, 500 Internal Server Error is IIS web server’s way of saying, “Something has gone wrong when I tried to display the page. Not sure what.

    Now, its time to see the exact reasons for the 500 errors.

     

    1. Permissions Error

    From our experience in managing servers, our Windows Experts often see PHP 500 internal server errors due to wrong permissions and ownership on website files. In Windows servers, 500 server error iis, every file and every folder has its own set of permissions, 500 server error iis. Again, some permissions are inherited from the parent folders too. And, when the PHP binary do not have enough permissions to execute the scripts, it can result in 500 internal server error.

    Similarly, ownership of the files also create problems. In Windows, specific users like IIS User, IIS WP User, etc. should 500 server error iis access on the website folders and files. For example, the IUSR account should have modify permissions on php scripts. And, when there are permission problems, website shows PHP errors.

     

    2, 500 server error iis. Bad PHP Settings

    Yet another reason for PHP internal server error is bad PHP settings, 500 server error iis. The PHP settings are specified in the configuration file at C:\PHP\PHP.ini. PHP binary take the values from this file while executing scripts.

    A classic example will be PHP timeout settings. When the website PHP scripts has to fetch results from external resources, PHP timeout values often cause trouble.  Most system administrators set timeout values in PHP to avoid abuse of the server resources. And, if the PHP script executes for a time longer than the threshold limits, it eventually results in 500 error.

     

    3. PHP module errors

    A very few 500 errors happen when the PHP module on the server as such becomes corrupt too. As a result, it results in processing failure of PHP scripts.

    Luckily, when the website reports the 500 error due to module failures, IIS often show a more specific error messages like:

     

    How we fixed PHP 500 internal server error in IIS

    Fixing PHP 500 internal server error 500 server error iis IIS need a series of steps. Let’s now see how our Dedicated Engineers fixed it for one of our customers and made PHP scripts running.

    The customer reported 500 internal server error on WordPress website running in IIS.

     

    1. Turning On Display errors

    While the error correctly suggested that PHP had caused 500 error code, it did not provide application-specific information about what caused the error. Therefore, the the first step of investigation was to turn ON display errors option. For this, our Dedicated Engineers followed the steps below.

    1. Using Windows® Explorer, browse to C:\PHP and open the Php.ini file in the PHP installation directory.
    2. Edit and set the display_errors = On directive.
    3. Save the file.
    4. Reset IIS using the command iisreset.exe

    After 500 server error iis on the errors, we reloaded the PHP and it showed a PHP parse error:

    Often browser settings only show friendly error messages. In such cases, we recommend customer to turn it Off. For example, in Internet Explorer Go to Tools, Internet Options, Advanced tab, and then clear the Show friendly HTTP error messages check box.

    Thus, it was a coding error on the PHP script. We suggested script modifications to customer and that fixed the error.

     

    2. Running PHP script locally

    Yet another way to find the exact error is to run the problem php script within the server. For this, our Support Engineers connect to the server via rdesktop and execute php script using the php.exe binary. It would show the  DLL’s that are having conflicts and causing the 500 error. We fix these conflicts and make the script working again.

     

    3. Correcting PHP settings

    In some cases, we need to correct the PHP settings to get the problem solved. Recently, when a customer reported problems with his website, we had to set the php directive open_basedir correctly to solve 500 Internal Server Error.

    Similarly, when PHP cgi scripts show up some warning, IIS7 still displays an HTTP 500 error message. Although the best method is to fix the PHP scripts, often changing the default error handling for FastCGI in IIS7 to “IgnoreAndReturn200” also work as a temporary fix. The exact settings will look as shown.

     

    4. Fixing PHP binary

    In some rare cases, the fix may involve complete rebuilding of PHP binary on the server. This happens mainly when the PHP program on the server becomes corrupt. However, in such cases our Dedicated Engineers always check the dependency of the package and do the reinstall. For control panel specific servers, we set the appropriate binary on the server.
