Greetings everyone.
I had the amp plugin running on ubuntu 14.04 nginx 1.4.6-1 and php 5.5.9, the database was hosted on amazon rds. After a catastrophic sequence of events and recovery I had the server running on ubuntu 16.04, nginx 1.10.0 and php7.0.8.
While among some other items that broke the AMP plugin started spewing out the following http 500 error. I’ve tried deleting the plugin files and reinstalling it. So far it has not worked. I’m at a bit of a loss at what to do with the error below. Any advice is welcome.
