Are you experiencing a WordPress 500 internal server error?
One of the most frequent WordPress issues is the internal server error. Many novices find the mistake quite aggravating because it needs more information. Not just WordPress websites might get the 500 internal server problem. Problems with plugins or themes mainly cause it, but it can also happen because of damaged files, PHP memory limits being reached, or coding errors. As the server side is where the error originated, it is also where the solution is found.
What Causes the Internal Server Error in WordPress?
Under certain circumstances, the entire website may function properly but the internal server problem appears only when you attempt to enter the WordPress admin area.
The “Internal Server Error” in WordPress is a generic error message that doesn’t provide specific details about the issue. It’s often caused by various factors, and troubleshooting may be needed to pinpoint the exact problem. Here are some common causes:
- Plugin or Theme Issues:
Incompatible plugins or themes can lead to conflicts, resulting in an internal server error.
Try deactivating plugins or switching to a default theme to identify the culprit.
- Corrupted .htaccess File:
The .htaccess file controls server configuration. If it’s corrupted or contains incorrect code, it can lead to internal server errors.
Rename or delete the .htaccess file and see if the error persists. WordPress will generate a new one.
- PHP Memory Limit Exhausted:
If your server’s PHP memory limit is exceeded, it can cause internal server errors.
Increase the memory limit in the wp-config.php file or contact your hosting provider for assistance.
- Corrupted Core Files:
Reinstall WordPress or replace the corrupted files.
- Server Configuration Issues:
Incorrect server configurations, such as PHP version mismatches or server module issues, can trigger internal server errors.
Check your server error logs for details and contact your hosting provider if necessary.
- File and Folder Permissions:
Incorrect file or folder permissions can cause internal server errors.
- Database Connection Problems:
Issues with the database connection, such as incorrect credentials or a corrupted database, can lead to internal server errors.
Check your wp-config.php file for correct database settings.
- Faulty .user.ini File:
If your server uses a .user.ini file for PHP configuration, a mistake in this file can result in internal server errors.
Review and correct the .user.ini file if present.
- Security Plugins:
Security plugins that block certain requests may trigger internal server errors.
Temporarily deactivate security plugins to see if the error persists.
- Exceeding Server Resource Limits:
If your website exceeds the allocated server resources (CPU, memory, etc.), it can lead to internal server errors.
Monitor your server resource usage and consider upgrading your hosting plan if needed. To troubleshoot, check the error logs on your server, usually found in the server’s error log file or the WordPress debug log. These logs can provide more specific information about the cause of the internal server error.
How to Fix the 500 Internal Server Error on Your WordPress Site
There are several ways to repair the 500 internal server problem on WordPress because it can happen for several reasons. To quickly repair the problem, I suggested going through the changes below in chronological order.
- Make a WordPress site backup.
Make sure you have a backup of your WordPress website first. Be cautious, as the last thing you want to lose is anything.
A simple code error might bring your website down. That’s why it’s so important to backup your WordPress website. You have two options for doing it: manually or using reliable WordPress backup plugins.
- Update Your Page
Try the easiest fix first—sometimes, just refreshing the page can solve the internal server problem.
- Remove all browser cache.
Experiencing the 500 internal server issue again only requires cleaning your cache and cookies. Occasionally, cache files can get damaged, thereby hindering your access to the website.
However, you should first use services like Is it Down Right Now to see if the site is down globally before proceeding. You can erase the cache in your browser if it’s down for you alone. Every browser has a distinct process for clearing its cache and cookies. By accessing the settings, you may delete them.
- Plugins Audit
Make sure your website is using the latest recent plugins by doing frequent plugin audits. Incompatible or out-of-date plugins might result in errors on your WordPress website due to compatibility problems.
5, Verify Your file.htaccess
In certain situations, you can access the.htaccess file and correct the issue. To access and fix the.htaccess file, follow the instructions below.
