Support » Plugin: Web Stories » A mandatory AMP HTML tag is missing from this document.

  • Resolved jesusdlg



    While checking the Search Console today I found an error that says:
    A mandatory AMP HTML tag is missing from this document.

    Is there something I need to check or disable in my page or web stories in order to prevent this to happen?

    Thank you!

  • More information on this:

    Falta la etiqueta obligatoria “head > style[amp-boilerplate]” o esta no es correcta.

    and this one:

    El atributo “media” no puede aparecer en la etiqueta “style amp-custom”.


    Sorry for the error message in Spanish, that was a copy from my search console

    @jesusdlg Hi there, thanks for posting your topic! I don’t see your stories URL displaying any validation errors. The URL passed Rich Results test and AMP test.

    – Could you provide your Site Health information and we can check for other conflicts? You can share privately if you prefer.

    As an aside, I notice that clicking the URL provided above actually directed me to It also appears (from the page source code) you are using Yoast SEO plugin.

    Please note we’ve changed the URLs from /stories/ to /web-stories/ before our 1.0.0 release.

    Since Yoast SEO caches the URLs in the database, you might still see old URLs.

    There will be a fix for this in our next release, but as a temporary workaround you can edit each story in the editor and click “Update” without making any changes.

    I just update the story as you mention.

    Will be checking other points later today/tonight. Thanks!
