Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
Please head over to your WordPress Dashboard > Rank Math > Status & Tools > Database Tools and click the Recreate Missing Database Tables button and see if that works for you: https://rankmath.com/kb/rank-math-status-and-tools/#recreate-missing-database-tools
If the issue persists, then your theme may be using a template for 404 pages. Please update this Rank Math file via FTP or CPanel’s file manager – wp-content/plugins/seo-by-rank-math/includes/modules/404-monitor/class-monitor.php
Then on line 53, change this:
$this->action( $this->get_hook(), 'capture_404' );
To this:
$this->action('template_redirect', 'capture_404' );
Once done, check again the 404 Monitor and see if it’s already logging them.
Please note that you may need to modify the code above each time you update Rank Math.
Let us know how it goes. Looking forward to helping you.
Thank you.
