Ok, allow me to explain the problem. We are using a forum called pnphpbb2, which was originally phpbb, a standalone forum. When they made it a postnuke module they did a very poor job. Thought it has a great amount of features it is still buggy with postnuke. Doesn't mesh well, wants to be a standalone still.
So I found an addon, a hack, to add to the coding for this forum. I added it and the gallery that I was adding didn't work. I was using version 1.2 of the forum when it was made for version 1.2a, so I deleted all the old forum files and uploaded all the new ones plus the gallery for 1.2a. All the forum posts/user info is not stored in folders, it's in a mysql database don't worry. Then with the upgrade the forum didn't work cause things were buggy. So I ran a new install and still had bugs. Ran an upgrade, still bugs. I guess pnphpbb doesn't like to upgrade. So I deleted all the 1.2a files and uploaded 1.2 again. The gallery is no go I guess, lotta work for nothing.
The forum looks like crap at the moment cause for some weird reason I can't fix the other look. When the site gets a new "theme" it'll look better.
