Please try this:

Choose your member theme once again by going to “BuddyPress > General Settings > Select theme to use for BuddyPress generated pages” in WPMU’s backend.

With a default BP install you should only see two theme choices: BuddyPress Default Member Theme (1.0.1)–this is the one you want–and, Skeleton BuddyPress Member Theme (1.2).

Choose the Default Member Theme and save your selection. Try visiting your site once again.
