How To Fix A Critical Error In WordPress?

-

Fixing a critical error in WordPress can be a bit challenging, especially if you are not familiar with coding and debugging. However, here are some steps you can follow to troubleshoot and fix a critical error in WordPress:

1. Check for Error Messages:

When a critical error occurs, WordPress usually displays an error message. Look for this message as it often contains useful information about what went wrong. If you see a message like "The site is experiencing technical difficulties," click on the 'Error Details' link to get more information.

2. Accessing WordPress Files:

To fix the error, you'll need access to your WordPress site's files. You can use an FTP client or your hosting provider's file manager to access the files.

3. Deactivate Plugins:

Plugins are a common cause of critical errors. If you can access the WordPress admin area, try deactivating all your plugins. If the error goes away, reactivate them one by one to find the problematic plugin.

  1. Using FTP:
    • Connect to your website using an FTP client.
    • Navigate to the "wp-content" folder.
    • Rename the "plugins" folder to something else (like "plugins_old").
    • This will deactivate all the plugins at once.
    • Check if the error is resolved. If it is, start activating plugins one by one to find the problematic one.

4. Switch to a Default Theme:

Your theme might be causing the error. If you can access the WordPress admin area, try switching to a default WordPress theme (like Twenty Twenty-One). If you can't access the admin area, you can do this by renaming your theme's folder in the "wp-content/themes" directory using FTP.

5. Increase Memory Limit:

Add the following line to your wp-config.php file to increase PHP memory limit:

php code
define('WP_MEMORY_LIMIT', '256M');

6. Check for Syntax Errors:

If you recently edited your theme's files or added custom code, check for syntax errors. Even a small typo can cause a critical error.

7. Check Server Logs:

Check your server's error logs. Your hosting provider should be able to assist you in locating these logs. They can provide valuable information about what caused the error.

8. Reinstall WordPress Core:

If none of the above steps work, you can try reinstalling WordPress. This will not affect your content, but it will replace core WordPress files in case any of them are corrupted.

Remember, if you're not comfortable with these steps, it's a good idea to seek help from a developer or your hosting provider's support team. Making a mistake while editing WordPress files can make the situation worse. Always back up your site before making any changes.
