Checked one by one activating and deactivating plugins. A plugin called ‘Self-Hosted Google Fonts’ was causing this issue. Make sure it gets compatible with web stories soon.
After temporarily deactivating the W3 total cache plugin, the test shows the following error.
The attribute ‘href’ in tag ‘link rel=stylesheet for fonts’ is set to the invalid value ‘//boomelomedia.com/wp-content/uploads/sgf-css/font-db31fc16750adf1a261588dbbb977096.css’.
Still the same kind of issue.
Hey, I also got an AMP validation error after the last update.
It says “The attribute ‘href’ in tag ‘link rel=stylesheet for fonts’ is set to the invalid value.”
