I have exactly the same problem. My theme on my dev site is moved down by 25px from the adminbar.css file, but the admin bar isn’t written by the call to the footer. It does appear in the wp-admin section.
I’ve tried adding add_action( ‘wp_footer’, ‘bp_core_admin_bar’, 1 );
to my function.php file as a first guess, but with no success. Anyone with any ideas would be helpful!
