How To Fix Your Sitemap appears to be an HTML page. Please use a supported item

Hello,

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

You shouldn’t need to change your theme. I have moved your question to your own thread so it will be easier for us to help you.

Could you give us more details about the issue? Also, you can try to check if it is just a plugin conflict by following this guide: https://rankmath.com/kb/check-plugin-conflicts/

Please let us know if you find the culprit.

Only the site admin would know and your users won’t be affected by this troubleshooting.

Looking forward to helping you.

Hello,

If you want, we could take a closer look at the settings. Please edit the first post on this ticket and include your WP logins in the designated Sensitive Data section.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:

You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

We really look forward to helping you.
