I installed fresh copy of wordpress today.
Installed buddypress and bbpress on it. Everything tiptop up to that point. Then i installed Gantry Framework and theme for it and bam - Everything is white. I backed out and deleted theme folder, switched to default theme. Looks fine.
Turned off both buddypress and bbpress. Installed gantry and it's theme again. Nope. Still white screen when switching to it.
Decided to tackle problem from other side. Deinstalled Everything. Installed wordpress again, this time i installed gantry first.
IT WORKS!! So happily i install buddypress, stupidly install forums without checking if it still works. Aaaaand.. it doesn't work.
Getting white screen again.
I added bigger memory in wp-config.
I renamed plugings folder and made new one and installed just gantry on it.
I looked through all functions.php i could find. Didn't find anything obvious ... for less obvious i'm not sure through :/
I'm still getting white screen.
