 * Hi,
 * All the pages have problems, i think it’s due to fonts in multilingual plugin.
   
   The website is: [http://www.thebranding-agency.com/?amp](http://www.thebranding-agency.com/?amp)
 * The error is :Invalid CSS stylesheet
    The attribute ‘href’ in tag ‘link rel=stylesheet
   for fonts’ is set to the invalid value ‘[http://www.thebranding-agency.com/wp-content/plugins/sitepress-multilingual-cms/res/css/language-selector.css?v=3.3.5&#8217](http://www.thebranding-agency.com/wp-content/plugins/sitepress-multilingual-cms/res/css/language-selector.css?v=3.3.5&#8217);.
 * Thanks for your help.

 * Its actually got to do with the AMP url.. there seems to be an issue with the
   plugin. Google seems to only validate an AMP url that ends in /amp (for pages).
   If you test the page on [https://search.google.com/search-console/amp](https://search.google.com/search-console/amp)
   but replace ?amp with /amp at the end of your page URL, you will be able to see
   if there are any issues on the page.

 * Hi [@manmaroon](https://wordpress.org/support/users/manmaroon/),
 * You are getting that issue because of a plugin named sitepress-multilingual-cms
   which is trying to add the stylesheet in AMP. But AMP does not allow to add custom
   stylesheets.
 * We will try to make it compatibility with our plugin soon.
 * Regards
