I originally commented out the code as suggested above, but I combined the WPAC_Nav_Menu_Walker class with the bootstrap nav walker I was using (see here https://github.com/twittem/wp-bootstrap-navwalker/tree/For-Bootstrap-2.3.2)
I am using bootstrap 2.x and wordpress 3.6
I used it to hide a menu item and its dropdown menu, so I’m not sure how it will work with individual links.
In my wordpress-access-control.php is is lines 37 to 303.
Replace with the following:
// We check to see if the class exists because it isn't part of pre WordPress 3 systems
if ( class_exists( 'Walker_Nav_Menu' ) ) {
add_filter( 'wp_nav_menu_args', array( 'WordPressAccessControl', 'wp_nav_menu_args' ) );
