Site Error after installing the plugin

Hello, we apologize for the issue you are facing after installing the plugin. It seems that you might be encountering a fatal error that has affected some installations after the 1.0.49 update of Rank Math. This issue typically arises due to conflicts with other plugins or themes, particularly if they are using an older version of Action Scheduler.

To troubleshoot this issue, you can follow these steps:

1. Check for Plugin Conflicts: Deactivate all other plugins except Rank Math and see if the issue persists. If the error goes away, reactivate your plugins one by one to identify the conflicting plugin.

2. Clear Cache: Make sure to clear all caches, including server cache, after making changes.

3. Advanced Fix: If you’re comfortable with code, you can try the following advanced fix:

   • Go to the Snippets menu in your WordPress dashboard and click Add New.
   • Name the snippet and add the following code:

     add_action( 'init', function() { delete_option( 'schema-ActionScheduler_StoreSchema' ); } );

   • Select ‘Only run in administration area’ and save changes.
   • Open your WordPress Dashboard in a new window and deactivate the snippet after activating Rank Math again.
   • Disable the Code Snippets plugin if you are not using it.

   
   
   

4. Check Server Settings: Ensure that your web server is configured correctly to handle requests and return appropriate error codes.

If these steps do not resolve the issue, please reply to this ticket, and a human agent from the Rank Math Support team will assist you further. Thank you for bringing this concern to our attention!
