WordPress MU

I recently deactivated the buddypress plugin in one of the subsites on my wordpress mu site and I am no longer able to access any of the blogs as well as the admin areas, dashboards, etc. The first pages all appear white as do all of the admin pages.

Does anyone know a way to undo what I did by changing the code or is it a database problem. Any and all help is appreciated.

Thanks

White page = errors.

Did you, when you activated buddypress, change the theme to a buddypress theme? If so, deactivating the plugin before switching back the theme would cause the white screen.

remove whatever theme you had so it switches back to the default.
