I am encountering a “There has been a critical error on this website”

Hello,

We apologize for the issue you are facing with the "There has been a critical error on this website" message while using the Rank Math SEO plugin. Thank you for detailing the troubleshooting steps you’ve already taken; it helps us understand your situation better.

Since you’ve already tried increasing the PHP memory limit, checking for plugin conflicts, enabling debugging mode, updating and reinstalling the Rank Math plugin, and checking file permissions, here are a few additional steps you can consider:

1. Check the Error Logs: Since you enabled debugging mode but didn’t find detailed information, ensure that your server’s error logs are also checked. Sometimes, the server logs can provide more insight into what might be causing the critical error.

2. Theme Conflict: Sometimes, the active theme can cause conflicts. Try switching to a default WordPress theme (like Twenty Twenty-One) to see if the issue persists.

3. Reinstall WordPress Core Files: If there are any corrupted core files, reinstalling WordPress can help. You can do this from the WordPress dashboard under Dashboard → Updates and then click on Reinstall Now.

4. Contact Hosting Provider: Since you are using PHP 8.1.29, ensure that your hosting environment is fully compatible with this version and that there are no server-level issues affecting your site.

If none of these steps resolve the issue, please reply to this ticket, and a human agent from the Rank Math Support team will take over and assist you further.

We hope this helps you get closer to resolving the issue!
