It's been like this for a couple of days, don't know why I haven't mentioned it before but, is NB looking weird for anyone else? Did I miss something about a bug?
Your firewalls/antivurses/add ons might be blocking something, like one of the scripts that NB uses or something.
Are any other websites showing up weird/differently? Specifically, are there other sites that use VBulletin that are showing up wrongly for you?
