Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
The notice is showing because WordPress v6.7 has changed how translations are loaded. However, we’ve already released the beta version where the issue has been fixed. https://rankmath.com/changelog/beta/
If you want, you can enable the Beta update by following this guideline:
https://rankmath.com/kb/version-control/#beta-updates
If you are unable to see an update, please clear Rank Math’s transients from WP Dashboard > Rank Math > Status & Tools > Database Tools > Remove Rank Math Transients: https://rankmath.com/kb/rank-math-status-and-tools/#rank-math-transients
Please clear the caches, server, and WordPress after updating.
You can disable the Beta updates once you update to the latest version and if the issue is fixed.
In case, you don’t want to update the beta versions, you can use the following filter code on your website to remove this notice:
add_filter( 'doing_it_wrong_trigger_error', '__return_false' );
Here’s how you can add filter/hook to your WordPress site: https://rankmath.com/kb/wordpress-hooks-actions-filters/
Hope that helps and please don’t hesitate to let us know if you have any other questions.
Thank you.
