Reading through this post. I'm wondering this is what I'm experiencing. My forum seems to work until I try to access Control Panel, which gives me a blank screen. Out of desperation and frustration, I've tried starting fresh on a newly formatted linux machine with a new install of the software (not using my old data to rule out corruption). To replicate the error, I'm using a freshly formatted ubuntu LTS LAMP server and am following the install instructions step by step. Everytime, I end up with a working forum with a broken control panel.

After reading this threat, it wasn't clear if your blank control panel pages ever cleared up, and if so, what did you do to fix that?

Thanks!
