Buddypress restore failed
Using buddypress, I imported my ning users. Then a blog.
Now I exported the entire system into a new wp, and restored it.
The users are messed up, two users have the wrong avatar, and when I try and delete them :

Fatal error: Using $this when not in object context in /data/web/4d/15/05/flossk.tuxfamily.org/htdocs/wordpress-test/wp-content/plugins/buddypress/bp-groups/bp-groups-classes.php on line 1053

Hmm…

That sounds like a PHP4/5 bug. What version of BuddyPress are you on?
