We will go over most of the eventual problems and their solutions.
How to Fix the “HTTP Error ” as a visitor?
As a visitor, the only thing you can do is check if a connectivity issue from your end causes the error. You can also apply the following actions as a website owner since these are the quickest checks. If the error is caused by a local problem from your end, the steps below can save you a lot of time from troubleshooting.
Reload the page
The “HTTP Error ” may be visible only for you, http error 500 php, in case there was a brief connectivity problem. The website itself may be working fine, but you might have tried to access it when there was a momentary downtime, or your network failed to establish a connection to the website’s server.
Try reloading the page in the same browser with the Reload button or by pressing the keyboard shortcut Command+R for Mac, or F5 (Control+F5) for Windows.
If the website loads correctly, http error 500 php, the issue was only temporary, and you can stop troubleshooting.
Clear your browser cache and cookies
When the website doesn’t open after reloading, your browser might be keeping expired or corrupted cache files and cookies. Reloading the page will not delete them, so you must clear them manually.

How to Fix the HTTP Internal Server Error from the website?
In the best-case scenario, the steps mentioned above will fix the problem. However, if the error persists, you may need to dig deeper into the issue since the error stems from the website itself.
As a site owner or webmaster, there are several checks you can do that can solve the “ Internal Server Error.”
Check the Error Logs of the Website
In many cases, misconfigured files or scripts are the sources of the website’s errors. The error logs can help you identify them easier.
Typically, you should http error 500 php such logs in your hosting’s control panel, http error 500 php. SiteGround users can find the Error log in the website’s Site Tools.
To access it, navigate to the Websites section in your Client Area. Open the Site Tools of the respective site, select Statistics and click on Error Log.
You will see the most recent errors on your website that the server detected. Each error will be recorded with a few key pieces http error 500 php information:
- The date and time of the error.
- Description of the error.
- Information about which folder or file is possibly generating the error.
Below, you can see an error log indicating a problem with the .htaccess file.
This record indicates that the problem is from the .htaccess file located in the root folder of the website. It also specifies that the error is related to an <IfModule> missing arguments, which means there is a syntax error.
Using this information, you can navigate to the specified folder from File Manager, edit the .htaccess file and correct the syntax error.
Keep in mind that the Error log records errors related to the server configuration. Errors caused by PHP misconfiguration and scripts are not recorded, as they happen on application-level.
PHP errors are recorded in php_errorlog. It is generated automatically in the folder of the offending PHP file, http error 500 php. On SiteGround’s hosting, the PHP error log is active by default. If you have previously deactivated it or your hosting hasn’t enabled it, read this guide on how to enable error reporting in a PHP script.
To inspect the PHP error log, you can use File Manager or FTP client. Navigate to the root folder, if the error is caused by a script located in the root folder. Open the file php_errorlog, where you can examine the errors.
The php_errorlog shows general PHP errors. However, you may need a more detailed log of the problem. If you have a WordPress website, you can also enable the debug log for WordPress that can show more information. For detailed steps on how to enable the WordPress debug log, see this guide.
Reset File and Folder Permissions
Another common openedge printing windows 2008 error no=2 that can cause the “HTTP Error” are incorrect file and folder permissions on your website, http error 500 php. If the permissions prevent visitors from opening the critical website’s files and folders, they may see the error page.
The standard permissions are for files and for folders. You can change them from the File Manager in your hosting panel or from an FTP Client.
For setting the permissions for WordPress sites, SiteGround clients can http error 500 php the Reset Permissions tool for WordPress in Site Tools.
If your website is using another type of application, read this guide on how to change permissions db2 sql error code 471 files and folders from File Manager.
Alternatively, if your hosting’s panel doesn’t have similar tools, you can change permissions from SSH or from an FTP Client.
Change the PHP version
An incorrect PHP version on your website may cause PHP scripts to time out or produce fatal errors. As a result, the website may return the “HTTP Error.”
Test switching the PHP version to an older or later version. If the error disappears, http error 500 php, it’s an indication that the previous version was wrong. Keep the site on the newly selected one.
SiteGround users can easily switch the PHP version with only a few clicks on Site Tools. For detailed steps, check this guide on how to switch to a different PHP version in Site Tools.
Inspect or regenerate the .htaccess file
A common cause of the “Internal Server Error” is a problem within the .htaccess file. If the file is corrupted, it defines an incorrect root folder or contains syntax errors, the usual result is the “HTTP Error” page.
Fix the syntax error in .htaccess
As an example of a syntax error, we can use the previously mentioned error from the error log.
To inspect the file, open the Site Tools of the website. Then, select the section raidcall flashctrl error enotlnstallflash and open File Manager.
Navigate to the website’s root folder, which is the site name/public_html. In our example, the name is sprers.eu, so the folder path is sprers.eu.
In this folder, you can find the .htaccess file. Select the file and then press Edit to open the code editor.
Now, you can inspect its code. As the error log points, the problem is from the <IfModule>. The issue is a syntax error because the module is missing a forward slash in the closing tag </IfModule>.
Add the slash and then save the changes with the Save button. Reload the website and it should now load properly.
Wrong website’s root folder defined in .htaccess
Another common error in .htaccess is incorrectly defined root folder for the website. Usually, http error 500 php, this is a result from one of the following cases:
- You transferred the website from another hosting provider where it resided on a subfolder.
- You developed the website on a subfolder and then moved it to the main domain folder in the same hosting.
- For a WordPress website, you installed a plugin that has changed the RewriteBase in .htaccess. The plugin may need extra configuration to work with the modified code but currently, the website is inaccessible due to the “ Internal Error”.
To illustrate the problem better, we can use the following example.
Notice the /dev path in RewriteBase. This code instructs the server to load the website from a folder named public_html/dev. Since the folder is non-existent, when you load a page from the website, it will produce the “Internal Server Error” screen.
To fix the problem, simply remove the subfolder path from RewriteBase so the code would look like this:
This is the default WordPress code defining the root folder for the website. Confirm the change in FileManager with the Save button and reload the website. The error shouldn’t appear anymore.
Regenerate the .htaccess file
Another standard troubleshooting scenario is to replace the .htaccess file with a new copy. To replace the file with a new copy, open File Manager, http error 500 php, navigate to public_html, select the file .htaccess and choose Rename.
You can choose any name for the file. For example, you can name it htaccess-old and create a new .htaccess file.
If the website is WordPress, access the WordPress dashboard, navigate to the section Settings, and open Permalinks. Just click on the button Save Changes, and your website will generate a new .htaccess file with the default WordPress code.
If your website is not WordPress, find the default .htaccess code for your specific application. Use the button New File in File manager and name the new file .htaccess. Paste the default code into .htaccess and save the changes.
After the new .htaccess file is set, reload the website again to see if the error is gone.
Repair the database or fix the database credentials
Another common problem that can cause the “ Internal Server Error” is a corrupted database of your website. You may consider restoring the database from a backup or repairing it.
For WordPress, the error may occur if the website fails to connect to the database. Make sure that the credentials are set correctly in the sprers.eu file.
For detailed steps, read this guide on how to fix the error ‘Establishing a Database Connection’ in WordPress.
Disable plugins for your WordPress website
A misconfigured plugin can also trigger the “HTTP Error” in WordPress. The standard procedure is to disable the plugins one by one until you find the culprit.
If the error is only on the front-end, but you still have access to the WordPress admin dashboard, you can hasp hl error 1031 the plugins from the section Plugins, http error 500 php. Then choose Installed plugins. From the drop-down Bulk actions menu, http error 500 php, select Deactivate. Check the box Plugin and press Apply to deactivate all plugins.
In many cases, http error 500 php, the error prevents you from logging into the WordPress dashboard so you may need to use an alternative way.
A popular suggestion you’ll find online is to rename the wp-content/plugins folder, http error 500 php. We don’t recommend this method as it may fix the “HTTP Error”, but cause other complications.
It is safer and more efficient to disable all plugins from Site Tools (if you are a SiteGround user) or from the database.
Read the following guides for detailed steps:
After the plugins are disabled, reload the website. If the website is fixed, it is a strong indication that http error 500 php error is caused by one of the plugins.
Proceed by activating the plugins one by one. When the faulty plugin is http error 500 php, the error will return. You can then disable the plugins again to access the dashboard and activate all plugins apart from the problematic one.
You may consider replacing this plugin with another one or contacting its developers to report the problem.
Change the theme for your WordPress website
A badly configured theme can also cause the “ Internal Server Error” in WordPress. To check if the theme is the problem, you will need to replace it with another one.
Usually, you can change the theme from the website’s WordPress dashboard. However, in many cases, the ongoing “HTTP Error” prevents you from logging in.
Read this guide on how to change the WordPress theme from the database for more information.
Increase the PHP Memory Limit of the Website
The “HTTP Error” may also be caused by PHP scripts that exceeded the memory limit of your oledb unknown error 0x800a0e7d. By default the limit on all SiteGround plans is set to M. However, your WordPress http error 500 php may be set to a lower value. To increase the memory limit, follow the steps from this guide on how to increase WP Memory Limit.
Restore a Backup of the Website
If none of the solutions helped solve the issue or you find them challenging to implement, you may consider initapp error inititalizing directx the website from a backup. Restoring the website will revert all changes that caused the error in the first place.
SiteGround users can check this detailed tutorial for the Website Backup Tool.
Check if your website contains large files
Another common reason for this error is having a very large file as a part of your website. On SiteGround’s shared hosting servers there is a size limit for files that can be opened through the web, http error 500 php. The limit is 8GB, and if your website includes a larger file, this will result in the above error.
Check your website’s files either via SSH, FTP, or File Manager to locate the one causing the problem. Very often, these are logs with PHP errors.
On SiteGround’s servers, a log file is created automatically if your site’s PHP scripts produce any non-critical errors or warnings during their execution. The log file’s name is php_errorlog, and it is located in the same directory as the script that produced the errors. Usually, http error 500 php, this would be your website’s root folder.
Contact the web hosting provider
Ultimately, the “ Internal Server Error” may not be caused by your website configuration. The MySQL server may be down, or the server may be overloaded. Contact your web hosting’s support team so they can check the server’s status and help further with the problem.
The HTTP “ Internal Server Error” can be very frustrating to deal with because of its unclear nature, http error 500 php. The problem may originate from a local issue or an error on the website or the server.
