Plugin support

Hello,

I apologize for the issue you are facing with your sitemap not being indexed in Google Search Console. It seems that the X-Robots-Tag: noindex header is indeed preventing Google from indexing your sitemap.

To resolve this issue, you can try the following steps:

1. Check for Custom Code: Ensure that there are no custom codes or settings in your theme or other plugins that might be adding the noindex directive to your sitemap.

2. Add a Filter: You can add a filter to your theme’s rank-math.php file to ensure that caching is disabled for the sitemap. Here’s how to do it:

   • Navigate to WordPress Dashboard → Appearance → Theme File Editor.
   • Select the rank-math.php file from the right sidebar.
   • Add the following code:

     add_filter( 'rank_math/sitemap/enable_caching', '__return_false' );

   • Click on the Update button to save your changes.

   

3. Clear Cache: After making these changes, make sure to clear your website cache and check if the sitemap is now accessible without the noindex header.

4. Check Robots.txt: Ensure that your robots.txt file does not have any rules blocking the sitemap. You can check this in Rank Math SEO → General Settings → robots.txt.

If you continue to experience issues after trying these steps, please reply to this ticket with any additional details, and a human agent from our support team will assist you further. Thank you for raising this concern!
