Re: Blank page after install Buddypress 1.1.2
If it wasn’t obvious, for every person who reports a problem, we need this information. Saying that you have the “same problem” is possible but unlikely.
If BP didn’t create its tables on activation, delete everything and try again — in a totally clean database (if only for testing purposes) with new files. Jeff’s elaborated on this point above. Something must have done to stop the install scripts running correctly; either a mistake on your part or an error on your server. Quite possibly if you are trying to use WPMU/BP on a virtual hosted server, you are going to quickly exceed memory and execution limits.
Manually installing the BuddyPress tables is only putting a band-aid over whatever the source of your original problem is; most likely that problem will bite you later.
