Hello,

Please try following the steps below and see if that works for you.

#1. Flush the Sitemap cache by following this video screencast:

#2. Exclude the Sitemap files of the Rank Math plugin in your caching plugin. The cache could be via a plugin or from the server. For plugins or Cloudflare, please follow this article:

#3. If the above steps doesn’t seem to work, kindly apply the following filter code to your site.

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

Here’s how you can add filter/hook to your WordPress site:

Hello,

1.

I checked index in Robot Meta in Rank Math SEO > Title & Meta > General but when I verify code source page I still have this on my pages.

The Robots meta option from General Meta in the Titles & Meta option is only the default value for new posts or pages. Posts, where changes have been made to the Robots Meta in the Rank Math meta box in the edit section, will take the individual set value.

For pages with Robots Meta still showing noindex please go to its edit area and change the Robots Meta to Index.

Kindly refer to this guide on how to submit a sitemap to Google: https://rankmath.com/kb/submit-sitemap-to-google/

We hope this helps. Please let us know if you have further questions or concerns.

Thank you.
