I hate the new Admin bar in WordPress, and while it’s easy to disable in your User profile, if you have a site with many subscribers and you don’t want them to be annoyed by the bar, or for some design reason you don’t want it to show, here is the code to place in your functions.php file:

/* Disable the Admin Bar for all but admins. */
if(!current_user_can(‘administrator’)):
show_admin_bar(false);
endif;

If you want to disable the admin bar completely, add this to your functions.php file:

/* Disable the Admin Bar for everyone. */
show_admin_bar(false);
