Remove jQuery from Theme

Removes jQuery from your frontend theme if no administrator is logged-in. jQuery will continue to work in you backend and when the admin toolbar is visible. Plugins which depend on jQuery will not be loaded either.

This plugin does nothing more but this:

function init_without_jquery() {
    if (!is_admin() AND !is_admin_bar_showing()) {
        wp_deregister_script('jquery');
        wp_register_script('jquery', false);
    }
}

add_action('init', 'init_without_jquery');
