BuddyPress.org

I’m currently running BP 1.2 on my WP 2.9.1 (single user ), after that I’ve made my old niss theme BP compatible (it worked like a charm).

After activating the external group plugin, I get this php error :

Warning: array_map() [function.array-map]: Argument #2 should be an array in /homepages/…./blog/wp-content/plugins/buddypress/bp-groups.php on line 2454

sorry if it’s a newbee question, i’m no php guru, far from it

thanks in advance for any help

cheers
