Reply To: Sitemap couldn’t fetch issues on multiple sites

Hello,

Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.

Please try to follow 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 don’t seem to work, kindly apply the following filter to your site.

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

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

Once done, please clear your website cache, remove all the submitted sitemaps, and resubmit only the main sitemap in the Search Console and see if that works for you.

Let us know how it goes. We look forward to hearing from you.

Thank you.
