Hi there,
I installed EasyDiscuss and had problems with the dropdown on settings and migrators it didn't want to open. Than I changed the admintheme and it workes only one time, after opening it I'm going back to the dashboard and tried it a second time and same problem. I found out that mod_pagespeed is cause the problem.
So far for all with the same problem - edit the .htaccess in root and put - ModPagespeed off - inside and it save the file. Now you can work with this 2 Menues - After this you have to put a # on it to load the Mod correctly -> # ModPagespeed off.
I hope there will be a better solution for it in the near future.
Cheers
Steve
