Some thoughts;
– Assuming you don’t want others creating blogs in your installation, and you’re on WPMU, go to Site Admin > Options – under Registration Settings – choose ” User accounts may be registered.”
– Deactivate the Blogs component in admin dashboard – BuddyPress > Components Setup – under Blog Tracking – choose disabled
