Hi All -
I've been working to find a solution to why Simple:Press broke on my WordPress installation - the answer: Google's Mod_PageSpeed plugin (for Apache).
I haven't found any documentation around t'web about this, so I'm posting here in the hope that I might save at least one other person's sleepless nights.
The symptons: Simple:Press's admin panel behaves oddly - such has when creating a new group (or forum or permission set): the group (forum, permission set etc) fails to be created and the control panel's menu stops responding to clicks.
The solution: add these items to your pagespeed.conf file:-
It's *quite* possible that you don't have to have the first line … but having just found that adding these three lines makes Simple:Press work again - I'm filled with so much joy that I'm not very interested in experimenting further today
