WoWI is under heavy load because of the 2.2 patch. I have some caching on the main page thats breaking the js and trying to figure out why. Only happens when things are under load and the caching is needed. All sub pages work fine though. If I disable the caching when the site is under heavy load then the site loads spiral out of control. So I'm working on it.
Working on a new server solution for wowi, we've grown so much and haven't done much to our servers.
