There has been a critical error on this website Rank Math

Hello,

Thank you for contacting Rank Math and sorry for any inconvenience this issue may have caused you.

To help troubleshoot this further, we’ll need to see your debug log to understand what is causing the critical error on the website and proffer a solution. The debug log is a file that records any errors or warnings that occur on your site. It can help us identify and fix the problem faster.

To share your debug log with us, please follow these steps carefully:

• Open your wp-config.php file. You can find it in the root folder of your site, usually in /public_html/ or /www/.
• Before the line that says /* That’s all, stop editing! Happy blogging. */, add this code:

  // Enable WP_DEBUG mode
  define( 'WP_DEBUG', true );
  
  // Enable Debug logging to the /wp-content/debug.log file
  define( 'WP_DEBUG_LOG', true );
  
  // Disable display of errors and warnings
  define( 'WP_DEBUG_DISPLAY', false );
  @ini_set( 'display_errors', 0 );

  This code will enable the debug mode and create a debug.log file in the /wp-content/ folder of your site.

• Go to your website and try to perform the action that caused the error again. This will trigger the error and generate the debug.log file.
• In the file manager of your cpanel or if you are using FTP, to to the /wp-content/ folder of your site and look for the debug.log file. It should contain some information about the error that occurred. You can get in touch with your web host, they will help you locate the log file.
• Send us a copy of the debug.log file. You can use a service like wetransfer.com to upload it and share the link with us.

We hope these instructions are clear and easy to follow. If you have any difficulty or questions, please let us know. We’re here to help you.

Thank you for using Rank Math.

Hello,

Thank you for contacting Rank Math support.

We might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section.

Please do take a complete backup of your website before sharing the information with us.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:

You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

Please make sure that the credentials you give us are admin-level so we can debug the situation fully.

Thank you.

Hello,

The issue was that a particular post on your website had incorrect data for the focus keywords in the database as they were in an array format instead of a string.

We have corrected the issue and the error message should no longer appear moving forward, after today.

Don’t hesitate to get in touch if you have any other questions.
