Hello c, PPNSteve, ConquerorTravel, TRDK29, and gooma2,
Mike here from PageFrog—happy to help! So sorry for the delayed response. I’ve been receiving hundreds (maybe thousands!) of emails since AMP launched last week.
I’ve found that many, many, many errors are caused by older plugins that violate AMP regulations in one form or another. Over time, hopefully developers of these plugins will release AMP compatible updates, but for the time being it’s causing a lot of trouble.
For example, various plugins can cut out the “https” portion which breaks AMP, plugins often inject javascript which breaks AMP, they could handle styling in a certain way which breaks AMP, etc.
In our latest update, we released a new feature called Force AMP Compliance which disables conflicting plugins for your AMP Pages. Head under Mobile Formats > Settings, then scroll down to AMP and check the box beside Force AMP Compliance.
Try that out and let me know if the errors go away!
