BuddyPress.org

I can’t figure this one out. I’m disabling my network RSS feeds. Each plugin I tried mainly works, except the activity feed on my root blog still shows posts. Is there a way to disable the activity RSS? Hopefully if I can, it will allow the activity to still show within the site. Plugins tested: Buddypress private community, Private buddypress, Private wp suit, Private wp, Private wp 2, Private only, and Disable RSS. (wp 3.0.1+mu+bp)

I’ve tried this code I got from http://buddypress.org/community/groups/creating-extending/forum/topic/disable-all-rss-feeds/ by putting it at the end in my ftp.
function bp_remove_feeds() {
remove_action( ‘wp’, ‘bp_activity_action_sitewide_feed’, 3 );
remove_action( ‘wp’, ‘bp_activity_action_personal_feed’, 3 );
remove_action( ‘wp’, ‘bp_activity_action_friends_feed’, 3 );
remove_action( ‘wp’, ‘bp_activity_action_my_groups_feed’, 3 );
remove_action( ‘wp’, ‘bp_activity_action_mentions_feed’, 3 );
remove_action( ‘wp’, ‘bp_activity_action_favorites_feed’, 3 );
remove_action( ‘wp’, ‘groups_action_group_feed’, 3 );
}
add_action(‘init’, ‘bp_remove_feeds’);

No results. Also I tried putting it at the end of the functions php file in appearance>editor in the dashboard. Is there a specific place to put it?
