Hello,
We apologize for the issue you are facing while trying to install Rank Math. The error message you provided indicates that there might be a problem with the class name in the plugin’s code, which can occur due to various reasons such as conflicts with other plugins or themes, or issues with the PHP version being used.
Here are a few steps you can take to troubleshoot this issue:
-
Check PHP Version: Ensure that your server is running a supported version of PHP. Rank Math requires PHP 7.0 or higher. You can check your PHP version by navigating to Tools → Site Health → Info in your WordPress dashboard and looking under the Server section.
-
Deactivate Other Plugins: Temporarily deactivate all other plugins except for Rank Math to see if there is a conflict causing the error. If Rank Math installs successfully, reactivate your plugins one by one to identify the conflicting plugin.
-
Switch Themes: Try switching to a default WordPress theme (like Twenty Twenty-One) to rule out any theme-related issues.
-
Reinstall Rank Math: If the above steps do not resolve the issue, try deleting the Rank Math plugin and reinstalling it from scratch.
-
Repair Action Scheduler: If you are encountering issues related to the Action Scheduler, you can use our Repair Action Scheduler plugin to fix it automatically.
If these steps do not resolve the issue, 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 raising this concern, and we hope to help you resolve it soon!
