Nu, asta vine in loc de loaderul de facebook js, probabil secventa asta :

(function (d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) { return; }
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_US/all.js#xfbml=1&appId=YOUR_APP_ID";
fjs.parentNode.insertBefore(js, fjs);
} (document, 'script', 'facebook-jssdk'));
