With the BuddyPress RC-2 now using WordPress MU 2.7.1, we’ve found that the BuddyPress Home theme shows a white screen when previewing. Themes can still be activated, they just cannot be previewed.

This appears to be an issue with WordPress MU 2.7.1 disagreeing with the hyphen “-” in the directory name of the theme. Ticket number 965 has been opened on the WPMU Trac to alert their team to this issue.

In the meantime, for those of you looking for a temporary solution, simply rename the directory “buddypress-home” to “buddypress_home” and you’re theme preview will work as per normal.
