Hey,

When i hit the Finish & Activate button when i install Buddypress i get this error -
Fatal error: Cannot redeclare bp_dtheme_register_actions() (previously declared in /home/marleytal/sportabello.com/wp-content/themes/bp-social/_inc/ajax.php:30) in /home/marleytal/sportabello.com/wp-content/plugins/buddypress/bp-themes/bp-default/_inc/ajax.php on line 77
