Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
I checked your sitemap but didn’t find any issues there.

Can you please try to follow these steps below?
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:
https://rankmath.com/kb/exclude-sitemaps-from-caching/
Once done, remove all previously submitted sitemaps from your GSC account and resubmit your main sitemap(sitemap_index.xml) and wait for Google to recrawl the sitemap.
Let us know how it goes.
Thank you.
Hi,
Thanks for checking. But I am still getting the error in the search console.
/sitemap_index.xml Unknown 18 Feb 2023 14 Feb 2023 1 error 0 0
Hello,
As my colleague pointed out there’s no issue with the XML that’s generated by Rank Math.
I would suggest resubmit the sitemap by following this step:
1. Sign in to Google Search Console
2. In the sidebar, select your website.
3. Click on ‘Sitemaps’ under the ‘Index’ section.
4. Under ‘Submitted sitemaps’, click on the sitemap you want to remove.
5. Resubmit the sitemap.
Hope that helps. Let us know if you need any other assistance.
Thank You
