BuddyPress.org

Did you copy the folders from “/wp-content/plugins/buddypress/bp-themes/” to “/wp-content/bp-themes/”? If so and you’re still seeing the error, you should either upgrade to BuddyPress 1.0.3 (just came out) or COPY (not move) the bp-themes folders into “/wp-content/themes/” – There’s a bug in BP1.0.2/WPMU2.8.1
