Sorry, this page is not valid AMP HTML

Hello,

Since last update of your plugin I’m having this error in almost all my AMP pages.

The problem is related with some internal redirection.

If you check this link https://www.google.co.in/amp/www.bezzia.com/medicina-nuclear/amp/ it redirects to the normal HTML version and not to the AMP version.

I have contacted my hosting and all works fine, here you can see the AMP version and wordks fine https://www.bezzia.com/medicina-nuclear/amp/

Regards,

The page I need help with: [log in to see the link]
