A mandatory AMP HTML tag is missing from this document.

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”.

Thanks

PS
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 https://internetcreativo.mx/web-stories/tendenciasseo2021/. 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!
