Benchola on "[Plugin: BuddyPress] MAJOR Problems Installing BuddyPress"

Reet.

I've had a search around the forums re BuddyPress and I can't find anything that has had the same problem that I have.

I've installed the BuddyPress plugin and have then gone through the five or six steps of setting it up. I have then clicked on 'Finalise & Activate' and all I get is this:

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 30720 bytes) in /home/thebrisb/public_html/wp-content/plugins/buddypress/bp-members/bp-members-functions.php on line 867

Now I cannot access my website or admin page at all and I keep getting the above error message. So.....how can I, either:

(a) fix the problem so that it works properly, or
(b) access the admin page so that I can deactivate / delete the plug-in altogether?

Your URGENT response would be appreciated.

Thanks
