Do you want to completely remove the BuddyPress admin bar from your site? It’s actually pretty easy.
To remove the admin bar, open up your favorite FTP program and go to your bp-custom.php file in your site’s theme. If you don’t have one, create a file called bp-custom.php. Then add the following line to the file:
define( ‘BP_DISABLE_ADMIN_BAR’, true );
Most themes leave space at the top for the admin bar, so this will present an issue. You will need to open the stylesheet for your theme and add the following:
/* AdminBar Removed – fixing gap */
body { padding-top:0px!important; }
