Hello,

I’m sorry to hear that you are facing issues with the Rank Math plugin causing HTTP 404 errors on your website. To completely uninstall Rank Math and resolve this problem, you can follow these steps:

1. Activate Rank Math if it is not already enabled.
2. Navigate to Appearance > Theme File Editor (for Classic Theme) or Tools > Theme File Editor (for Block Theme) in your WordPress admin area.
   
3. Add the following code to your theme’s functions.php or rank-math.php file:

   /**
    * Filter to remove Rank Math data from the database
    */
   add_filter( 'rank_math_clear_data_on_uninstall', '__return_true' );

   Make sure to click the Update File button after adding the code.
   

4. Deactivate and then delete the Rank Math plugin from the Plugins page. You will see an irreversible action notice due to the added filter.
   
5. After deleting Rank Math, you can check your database to ensure all Rank Math files are removed.
