What a freakin’ error that is huh? I kept getting it while trying to work on my 3-year old usability testing service.
Turns out it’s a conflict with Comatose and rails authentication. Here’s the fix:
Add ‘unloadable’ to line 3 of comatose_admin_controller.rb
# The controller for serving cms content...
class ComatoseAdminController < ActionController::Base
unloadable
