HOW TO: Hide Admin Nag Messages

The more plugins you install, the more nag messages you’ll get.

One simple way of hiding these is to add this script to your theme functions file:

add_action('admin_enqueue_scripts', 'pands_admin_theme_style');
add_action('login_enqueue_scripts', 'pands_admin_theme_style');
function pands_admin_theme_style() {
    if (current_user_can( 'manage_options' )) {
        echo '<style>.wrap .notice { display: none; }</style>';
    }
}
