Activity

Thanks for reply, I am trying to edit the profile activity stream. It filters out in the Side-Wide Activity and following(I use follower), but only cannot filter out in a user’s profile activity stream (Wall and News Feed) when replace with <?php if ( bp_has_activities( bp_ajax_querystring( ‘activity’ ) . ‘&action=activity_update’ ) ) : ?> on the activity-loop.php.
Could you tell me how can I solve this problem? I was thinking use remove function to remove those functions, can I do that?
