Hello, I've never experienced this problem before, and it just came to our attention because a client was trying to access our page and couldn't see much of the javascript. He was navigating to http://www.mysite.com, when we've always just gone to http://mysite.com. There appear to be no problems server-side, as in both url's are poin...
