Hello,
We apologize for the issue you are facing with Rank Math. It seems that you might be encountering a conflict that is causing the error when trying to work with posts. This can happen due to various reasons, such as compatibility issues with other plugins or themes.
To troubleshoot this issue, we recommend following these steps:
-
Check for Plugin Conflicts: Deactivate all other plugins except Rank Math and see if the issue persists. If it resolves the issue, reactivate the plugins one by one to identify the conflicting plugin.
-
Theme Conflict: Switch to a default WordPress theme (like Twenty Twenty-One) to check if your current theme is causing the issue.
-
Clear Cache: Make sure to clear any caching plugins you may have installed, as well as your browser cache.
-
Check PHP Version: Ensure that your server is running a compatible version of PHP for Rank Math. You can find more information about compatible PHP versions in our documentation.
If the problem continues after trying these steps, please reply to this ticket, and a human agent from the Rank Math Support team will take over and assist you further.
Thank you for raising this concern!
