Title: Amp Error on Categories Last modified: February 21, 2020 --- # Amp Error on Categories * [calgarytech](https://wordpress.org/support/users/calgarytech/) * (@calgarytech) * [6 years, 4 months ago](https://wordpress.org/support/topic/amp-error-on-categories/) * see: [https://www.urtech.ca/downloads/AMPErrors.jpg](https://www.urtech.ca/downloads/AMPErrors.jpg) * As you can see Google does not like my Categories on AMP anymore. I tried clearing the CACHE but Google was still not happy (perhaps I have to wait longer). * When I expand the error in GOOGLE SEARCH CONSOLE, it just states: * **Linked AMP version is invalid It won’t appear in Google Search results. Referenced AMP URL is not an AMP * I do not see any errors appearing on mobile browsers, including categories, so I don’t know what Google does not like about them. * Thoughts? * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Famp-error-on-categories%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 9 replies - 1 through 9 (of 9 total) * Plugin Author [Ahmed Kaludi](https://wordpress.org/support/users/ahmedkaludi/) * (@ahmedkaludi) * [6 years, 4 months ago](https://wordpress.org/support/topic/amp-error-on-categories/#post-12463234) * We checked your issue.
