I´m getting a blank page also when trying to set up the forum part of the buddypress.
First i get this message:
http://yfrog.com/5sbuddy1j

Then i reinstall and follow the steps to come to this:
http://yfrog.com/0zbuddy2lj

As you can see, i cant make any groups or nothing in the setup, any suggestions what i can look for?

Regards
