tb_show is not defined in advance custom field

Did you also add wp_enqueue_script('media-upload') in functions.php ?

I tried this and it’s working:

function load_admin_things() {
    wp_enqueue_script('media-upload');
    wp_enqueue_script('thickbox');
    wp_enqueue_style('thickbox');
}

add_action( 'admin_enqueue_scripts', 'load_admin_things' );
