 * This error came up and now the AMP module in WordPress dashboard is just circling.
   I chose the simple, Reader option.

 * Many thanks for sharing your Site Health information. From inspecting the details
   I don’t see anything obvious that may be causing this problem. Can you share 
   if the same occurs when temporarily deactivating the AMP plugin?

 * I worked on it per your instructions on Saturday. Working okay now although still
   only 25 out of a possible 100 on Mobile Page Speed.

 * Great to hear that it’s working ok now. Based on your comments it sounds like
   you used the Health Check & Troubleshooting plugin to successfully determine 
   the cause. Can you share any comments or findings on what the issue was in your
   case?
 * > only 25 out of a possible 100 on Mobile Page Speed.
 * I’m see a huge increase in performance on your AMP URLs. I suspect you may be
   referring to your non AMP URLs. You can check the below yourself using [http://www.web.dev](http://www.web.dev).
