I am using WP 2.9.2 and installed Buddypress when i activated it I got this error message:

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 7680 bytes) in /home3/xxxxx/public_html/xxxxxxx/wp-includes/registration.php on line 103

my website is hosted a Bluehost.com and the xxx’s represent date that is blanked out for since the site is in beta – no peeking!

I thought this had blown my work all away however I simply renamed the Buddypress plug-in folder and wp-admin loaded again. Phew!
