looks to me like the following part is missing inside the "head" section of your template:
<?php
// automatically include optional WB module files (frontend.css, frontend.js)
if (function_exists('register_frontend_modfiles')) {
register_frontend_modfiles('css');
register_frontend_modfiles('js');
} ?>
So i assumee there must be JS-Error-Messages also ... Using FireFow? Use FireBug oder WebsiteDeveloper Plugin
