Hello,
Thanks for contacting us, and sorry for any inconvenience that might have been caused due to that.
I checked the sitemap URL of your website and it appears to be blank on my end and this is why you’re encountering the errors on GSC and sitemap validator as well.

What you’re probably seeing is the cached version of your sitemap. Please try clearing your browser’s cache or try visiting your sitemap URL using your browser’s incognito mode.
I can see that you’re using NitroPack plugin currently. Can you please confirm if you’ve excluded your sitemap from NitroPack plugin? If not, please try excluding your sitemap URL by following the guide I’ve shared below:
https://help.nitropack.io/en/articles/3406180-excluded-urls
If the issue still persists, assuming you are using the latest version of all the plugins and the themes (please update if not yet), it would seem like a conflict with one of the plugins or the theme you are using.
To determine that, please follow this troubleshooting guide:

Here is a video you can follow as well: https://www.youtube.com/watch?v=FcIWRhcUP2c
Only the site admin would know and your users won’t be affected by this troubleshooting.
Let us know how it goes. Looking forward to helping you.
Thank you.

Hi.
I want to share something with you.
I created a Sitemap mannually, and it worked with Google Search Console
https://enterexdiabetic.com/sitemap.xml
But, I really want it can works with rank math.
Hello,
When I checked your Rank Math main sitemap, it displayed without errors. You can now use the default Rank Math sitemap (https://enterexdiabetic.com/sitemap_index.xml) in Google Search Console. Screenshot:

If the sitemap stops displaying again, please check the following URL as it may show what error is affecting your sitemaps: https://enterexdiabetic.com/?sitemap=1
Hope that helps. Please let us know if you have questions.
Hi.
I´m still gettin the issue.
Check this loom: https://www.loom.com/share/2f762202674f4271ab3a01e649e7ad8f
The URL you gave me shows an error and, I added the index sitemap on Google Search Console and still is empty
Hello,
Can you please try clearing your browser cache or try viewing sitemap using your browser’s incognito mode to see if it’s loading? As I can see that your sitemap is loading perfectly fine from my end.

Also, please try clearing your website cache, including any server level caches present. Once done, please try re-submitting your sitemap to GSC to see if that works for you.
Looking forward to helping you.
Thank you.
Hi.
I did it, cleaned my cache but GSC still don´t recognice the rank math Sitemap, but the manual sitemap do https://enterexdiabetic.com/sitemap.xml
If I validate the manual XML it´s ok https://www.xml-sitemaps.com/validate-xml-sitemap.html but, if I try to validate the rank math sitemap, I see an issue message
Hello,
Upon checking your sitemap page, I saw a blank page. After further investigating your sitemap I found 2 issues on my end:
1. It seems your sitemap is still heavily cached. After flushing the sitemap cache, the content of the sitemap appears right away. Kindly check with your hosting provider if you have other server-level caching services like Cloudflare and ask them to clear the sitemap cache and ensure the sitemap path is excluded.
2. All of your 4 sitemap URL variations don’t redirect to a final variation as you can see in my screenshot below:

Please follow this guide and redirect to a final variation:

Looking forward to helping you with this one.
