Like many others apparently, I am trying to get FEC to work on my newly upgraded 1.5.5 install (from 1.3.9). CSS/JS loader seems to be working fine.

I have gone through a lot of this thread, some people seem to have it working on 1.5.5 and others are saying it is just incompatible. Does anyone have any further information about FEC and Zen 1.5.5? I tried FEC 2.1.4 and 2.1.8.

Currently (with 2.1.8) FEC config shows up in the admin menu, but doesn't seem to be loading up completely:
Attachment 16465

My error logs are empty, so I don't even know where to begin.

PHP 5.4.43 (Zend: 2.4.0)
