There is something wrong with the schema

Hello,

We apologize for the issue you are facing with the schema on your site. Thank you for providing detailed information about the problem.

To address your concerns:

1. Is Rank Math injecting this default schema behind the scenes?
   Yes, Rank Math automatically generates certain schema types based on the content and settings of your site. This can sometimes lead to duplicate schema if custom schema is also implemented.

2. How can I permanently disable all auto-generated schema for this page?
   You can use a filter to disable the auto-generated schema for specific pages. Here’s a code snippet you can add to your theme’s rank-math.php file to remove all schema from your homepage:

   add_filter( 'rank_math/json_ld', function( $data, $jsonld ) {
      if ( is_front_page() ) {
          return [];
      }
      return $data;
   }, 99, 2);

   This will ensure that no schema is generated for the homepage, allowing only your custom schema to be used.

3. Is there a hook/filter I should apply site-wide?
   If you want to disable schema site-wide, you can modify the filter to apply it globally instead of just for the homepage. However, be cautious with this approach as it will remove all schema across your entire site:

   add_filter( 'rank_math/json_ld', function( $data, $jsonld ) {
      return [];
   }, 99, 2);

   This will prevent Rank Math from generating any schema markup.

Please ensure to back up your site before making any changes to the code. If you continue to experience issues or need further assistance, please reply to this ticket, and a human agent from our support team will take over and assist you further.
