BuddyPress.org

Yes I have everything enabled. Unfortunately, I just installed a new theme to try it (Buddymatic) and when I activated it I got the following error.
Fatal error: Cannot redeclare bp_dtheme_ajax_addremove_friend() (previously declared in /home/ordinar5/public_html/coupons/wp-content/plugins/buddypress/bp-themes/bp-default/_inc/ajax.php:334) in /home/ordinar5/public_html/coupons/wp-content/themes/buddymatic/_inc/ajax.php on line 63

Can you tell me what happened and how I might fix this?
