site crashes after activate plugin

Hello,

I’m sorry to hear that you’re experiencing issues with your site crashing after activating the Rank Math plugin. This can sometimes happen due to conflicts with other plugins or themes, or because of an older version of the Action Scheduler being used by another plugin.

Here are a few steps you can try to resolve the issue:

1. Check for Plugin Conflicts: Deactivate all other plugins and then activate Rank Math to see if the issue persists. If it works, reactivate your plugins one by one to identify the conflicting plugin.

2. Update Everything: Ensure that WordPress, your theme, and all plugins are updated to their latest versions.

3. Clear Cache: If you have any caching plugins or server-side caching, clear all caches after making changes.

4. Use Code Snippets: If you’re comfortable with code, you can add a snippet to delete a specific option that might be causing the issue. Here’s how:

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

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

   • Select ‘Only run in administration area’ and save it.
   • After saving, deactivate the snippet and try activating Rank Math again.

5. Professional Setup Service: If you’re still having trouble, we recommend considering our professional setup service, which ensures that your plugin is set up correctly according to the latest SEO standards. You can find more information about this service here.
