Common Causes of a 500 Internal Server Error in WordPress

Plugin or theme incompatibilities, .htaccess file corruption, PHP memory limit reached, affected WordPress core files, and server problems are all potential causes of a 500 Internal Server Error in WordPress.

Plugin or Theme Conflicts

One or more of your add-ons or themes might be corrupted. A plugin’s incompatibility with the most recent version of WordPress or other plugins may become apparent during the installation or upgrade process. Locating the problematic add-on, theme, or plugin is essential for fixing the issue.

Corrupted .htaccess File

A 500 Internal Server Error in WordPress may also be brought on by a corrupted .htaccess file. This file determines how the server responds to requests and where the requests should go. This might be due to a syntax problem or incomplete code in the file. A new .htaccess file may be generated to fix the problem.

Exhausted PHP Memory

Another usual reason for the problem is that PHP’s memory limit has been hit. This happens when there is a memory overflow caused by the PHP programs executing on the server. To fix this, edit the wp-config.php file and increase the PHP memory limit.

Corrupted WordPress Core Files

The WordPress core files being corrupted is another common cause of the 500 Internal Server Error. This may occur if the files get corrupted when updating or from malicious software. The problem may be fixed by reinstalling the WordPress core files.

Server-related Issues

Errors can also be caused by server-related issues like congestion, downtime, or improper configuration. Communicating with the hosting provider to handle server-related problems is essential if the error continues after other potential causes have been eliminated.

Determining what caused the error and fixing it, you can get your WordPress site back up and running smoothly.

How to Fix a 500 Internal Server Error in WordPress

The following is a list of methods that may be used to assist in fixing 500 internal server error in WordPress:

Method 1: Deactivating Plugins and Themes

The 500 Internal Server Error in WordPress is often brought on by plugins and themes that are not compatible with each other. Follow these methods to disable them on your system:

• If a plugin or theme in your WordPress is responsible for the issue, log in and go to the relevant part of the WordPress dashboard.
• Turn off all plugins or themes you may have.

• Activate the site’s default theme.

• Verify whether the problem still exists. If so, try activating each plugin and theme until you locate the problematic element.

Method 2: Regenerating the .htaccess File

Another common reason for the 500 Internal Server Error is a corrupted .htaccess file. Here’s what you need to do to create a new .htaccess file:

• Select Settings > Permalinks in your WordPress dashboard.
• Just hit “Save Changes” and ignore the other edit fields. When you do this, WordPress will create a new .htaccess file with its predefined rewrite rules.

• Verify that the 500 Internal Server Error has been fixed on your website. If so, the problem was caused by your old .htaccess file. Otherwise, go to the following steps.

Make sure WordPress can either create or write to the .htaccess file if the problem persists after you’ve resolved it. Incorrect directory and file permissions might prevent the .htaccess file from being updated.

• Access your site using cPanel to make changes to the .htaccess file manually.

• Once you’re connected, look for the .htaccess file in the same directory as your other WordPress files and directories (such as wp-content, wp-admin, and wp-includes).
• The current .htaccess file should be renamed .htaccess_old.

• In the same folder, create a new .htaccess file.
• Simply create a new .htaccess file, put the pre-existing rewrite rules from WordPress into it, make any necessary changes, and then submit the file back to the server.
• Verify that the issue has been fixed on your website.

The internal server issue should now be resolved so that you may check your website. You could be proud of yourself for fixing the Internal Server Error if this were the case.

Method 3: Increasing PHP Memory Limit

If those solutions don’t work, PHP has reached its memory limit. The maximum memory that may be allocated to a single PHP script is limited by the PHP memory limit. A 500 Internal Server Error in WordPress may be generated if a script attempts to consume more memory than is available.

The wp-config.php file can be found in the root directory of your WordPress installation, and it is there that you may modify the PHP memory limit.

• Log in to your site using the file manager provided by your web server.
• Find the wp-config.php file in your WordPress installation’s root directory.

• Use the “View/Edit” option that appears when you right-click the file.

• Find the following line of code: define(‘WP_MEMORY_LIMIT’, ’64M’);
• Substitute a larger value, such as 128M or 256M, for the 64M currently set. Make sure to type an “M” for megabytes.
• Update the wp-config.php file and save your changes before uploading it again.

Now, verify that the 500 internal server issue no longer appears after raising the PHP memory limit.

Method 4: Reinstalling WordPress Core Files

Corrupted core files in WordPress might be the source of the 500 internal server issue if none of the aforementioned solutions work. This may occur when an update fails or when malware is present.

Here’s what you need to do to reinstall WordPress’s core files:

• Get the most recent release of WordPress from its home page.
• Get the WordPress archive and unpack it on your PC.
• Log in to your site using the file manager provided by your web server.
• Protect your WordPress site by creating a backup of your files and database.
• Remove everything from your WordPress installation except the wp-content directory.
• The extracted WordPress files and folders must be uploaded to the main installation directory.
• Visit your site to finish the process of installation.

You should verify that the 500 internal server error has been fixed after reinstalling the WordPress core files.

Method 5: Contacting Your Hosting Provider

If none of them work, there may be a server-side problem causing the 500 internal server error in WordPress. For help with this matter, you should contact your hosting company.

Make sure you provide the following details when contacting your hosting provider:

• A link to your website
• Describe the problem and what you’ve done to fix it so far.
• Any error messages you’ve gotten, including that 500 internal server error message

Get in touch with your hosting provider for assistance in troubleshooting and repair.
