BuddyPress.org

I would like to use it on http://vivre-en-autarcie.com. I run wpmu 2.7 + BP RC-1.

I install the plugin version for RC-1

By activating the plugin, I got following error ;

Warning: include_once(/homepages/17/d252975120/htdocs/wp-content/plugins/bp-invitefriends/) [function.include-once]: failed to open stream: No such file or directory in /homepages/17/d252975120/htdocs/wp-settings.php on line 545

Warning: include_once() [function.include]: Failed opening ‘/homepages/17/d252975120/htdocs/wp-content/plugins/bp-invitefriends/’ for inclusion (include_path=’.:/usr/lib/php5′) in /homepages/17/d252975120/htdocs/wp-settings.php on line 545

thanks for any advice
