My site is live and heavy traffic, I want to avoid “going down” again… * I have your plugin “rolled back” to a previous version (newest update avail) * Can I achieve the same results without deactivating Rank Math but instead of, simply update Rank Math to latest version with the add_action( snippet active for admin? * Plugin Author [Rank Math SEO](https://wordpress.org/support/users/rankmath/) * (@rankmath) * [5 years, 12 months ago](https://wordpress.org/support/topic/fatal-error-3655/#post-13519459) * Hello [@shirtguy72](https://wordpress.org/support/users/shirtguy72/) * Yes, please run it once when the Rank Math is disabled and then remove the Code Snippets plugin. * Once that is done, you can safely activate the Rank Math plugin. * Do take a complete backup first though. * Hope that helps. Thank you. * [Jimmy Lee](https://wordpress.org/support/users/shirtguy72/) * (@shirtguy72) * [5 years, 12 months ago](https://wordpress.org/support/topic/fatal-error-3655/#post-13519557) * That worked, thanks! But I can honestly say: I don’t want or need all those added tables with the new update. I will be rolling back to previous version. Still a 5Star plugin but slightly turned off by all the (extras) some won’t/don’t need. * Plugin Author [Rank Math SEO](https://wordpress.org/support/users/rankmath/) * (@rankmath) * [5 years, 11 months ago](https://wordpress.org/support/topic/fatal-error-3655/#post-13529398) * Hello [@shirtguy72](https://wordpress.org/support/users/shirtguy72/) * You can simply turn off the Analytics module if you do need that data inside your WordPress admin area. * Hope that helps.

Thank you. * P.S. The issue does not happen on all the installations but where some other plugin left incorrect DB tables.
