Hello,
Thank you for contacting Rank Math and sorry for any inconvenience caused.
I checked the URL you shared and it seems valid from my end, here is a screenshot:

Please ensure that the sitemap you have submitted is the main sitemap file which is /sitemap_index.xml
. If you have submitted any other on your GSC, please remove all and only resubmit only the main one.
Before resubmitting your sitemap, please exclude the Sitemap files of the Rank Math plugin in your caching plugin. Please follow this article: https://rankmath.com/kb/exclude-sitemaps-from-caching/
Once done, refresh your sitemap by flushing the Sitemap cache as shown in this video screencast: https://i.rankmath.com/pipRDp
That should fix the issue. Please let me know if that does not. We are here to assist.
Thanks a lot,i made all these steps .. i will see if this helps within the next days.
in the xml there are still absulute and relative paths..
bit i will see if google is able to catch it correctly…
Thanks and best wishces, Arno

Hello,
Thank you for the update.
I also wanted to add that usually, this issue is with Divi’s relative images feature. If you are using relative images, it will show that error in Google Search Console. Could you please try altering the image to a different type and see if the issue persists?
I hope that helps. Thank you, and please don’t hesitate to contact us if you need further assistance.
