Re: Blank page after install Buddypress 1.1.2
Okay, just to make sure, you are running WordPress Mu and not single-version WP, correct?
Since above you indicate that this is a clean install, I would suggest starting over from scratch once more. This means deleting the MySQL DB ( I assume that there is no data worth saving since you said that this is the first time you had installed WPMU). Next, reinstall WPMU and fully test it before installing BuddyPress. Once you’ve determined WPMU is functioning properly, then install and activate BP. Choose the default BP theme. Do not install any other plugins until you have verified that BP is functioning properly.
To make sure that you install both WPMU and BP properly, read the readme.txt files that come with each application.
