Finally fully converted my forum to xf, and I am getting this error on the live version when I open a overlay:
XMLHttpRequest cannot load http://fnintendo.net/xenforo/js/xenforo/comments_simple.js?_v=6256ffdf. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://www.fnintendo.net' is therefore not allowed access.
Anyone knows how is this fixed?
Edit: ok, just found it works fine on fnintendo.net, but not on www.fnintendo.net.
