Actually, the only "integration" between PP and phpbb2 has been the user database. The PP theme has stayed the same and there is no link to either the forum from PP or vice-versa.
I also cannot upload photos. No matter what upload settings I change in the admin it still sets a file limit of 1kb. It seems to save them properly (when saved I can see the new value in the admin) but there is no change in the PP forum itself.
