Hello,
We apologize for the issue you are facing with the PHP warning on your server. This warning indicates that there is a problem with a regular expression in the Rank Math plugin, specifically in the class-post-variables.php file.
To resolve this issue, we recommend the following steps:
- Update Rank Math: Ensure that you are using the latest version of the Rank Math plugin. Updates often include bug fixes that may resolve such warnings.
- Check for Plugin Conflicts: Sometimes, conflicts with other plugins can cause issues. You can deactivate all other plugins and see if the warning persists. If it resolves, reactivate them one by one to identify the conflicting plugin.
- Review Custom Code: If you have added any custom code or snippets that interact with Rank Math, review them to ensure they are not causing the issue.
- Contact Support: If the problem continues, please reply to this ticket with your site URL so that a human agent from our support team can assist you further.
Thank you for bringing this to our attention!

Hi, can you suggest a solution to this (other than AI reply)?
thanks,
Hello,
The error message preg_match_all that you shared is most likely caused by a mismatch in the parentheses of some of your focus keywords.
Sometimes, you might use parentheses to group words together or to indicate a variation; however, if you forget to close a parenthesis, or if you have an extra one, this can cause the error message to appear.
To fix this problem, you need to check the focus keyword of the page and make sure that every opening parenthesis is matched with a closing one.
Looking forward to helping you.
Hi, so how do I find the post / page where the error error is? there are 1000s of posts on the site…

thanks,
Hello,
How was the error generated? Did it generate for a specific post or page? If it does, then that page has the broken focus keyword format.
Looking forward to helping you.
