All of a sudden my website sitemap stopped working and AMP Issue

Hello,

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

As for your AMP issue, can you please let us know which specific AMP issue you are facing so we can provide a solution accordingly? Kindly share some screenshots of the issue if there are any.

Looking forward to helping you.

Hello,

I’ve tested your web stories using Google’s AMP tool, and there are tag errors which you should fix.

Could you please confirm which AMP plugin you’re using on your site?

Meanwhile, 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 this goes.

Thank you.

Hello,

In this case, kindly contact the support folks from that plugin to further assist you and ensure the AMP page is validated properly.

Looking forward to helping you with this one.
