How to Fix WordPress Website Critical Errors


WordPress is a popular content management system that powers millions of websites around the world. However, like any other software, WordPress is not immune to errors and issues. One of the most common and critical problems that WordPress website owners may encounter is the occurrence of critical errors.

Identifying Critical Errors

When a critical error occurs on your WordPress website, you will usually see an error message or a white screen of death. These errors can be caused by various factors, such as incompatible plugins or themes, server issues, or corrupted files.

Here are some common critical errors that WordPress users may encounter:

  • Internal Server Error
  • White Screen of Death
  • Error Establishing a Database Connection
  • HTTP Error 500

Fixing WordPress Critical Errors

Now that you know what critical errors are, let’s discuss the process of fixing them:

1. Identify the Error

The first step in fixing a critical error is to identify the specific error message or symptom. This will help you understand the root cause of the problem and find the appropriate solution.

2. Disable Plugins and Themes

Incompatible or outdated plugins and themes are often the culprits behind critical errors. To identify the problematic plugin or theme, you can disable all of them and then enable them one by one until the error reoccurs. Once you identify the problematic plugin or theme, you can either update it or find an alternative.

3. Check File Permissions

Incorrect file permissions can sometimes cause critical errors. Make sure that the files and directories on your WordPress website have the correct permissions. The recommended permissions are usually 644 for files and 755 for directories.

4. Repair Corrupted Files

If your critical error is caused by corrupted files, you can try repairing them. You can use the built-in WordPress file repair tool or manually replace the corrupted files with fresh copies from a backup.

5. Increase Memory Limit

Some critical errors can be caused by insufficient memory limit. You can increase the memory limit by editing the wp-config.php file or contacting your web hosting provider for assistance.

6. Contact Support

If you have followed the above steps and are still unable to fix the critical error, it is recommended to contact the WordPress support team or your web hosting provider for further assistance. They will be able to help you diagnose and resolve the issue.


Dealing with critical errors on your WordPress website can be frustrating, but with the right approach, you can fix them and get your website back up and running smoothly. Remember to always keep your WordPress core, plugins, and themes updated to minimize the risk of critical errors in the future.
