And... to add to pyonir's list, when you clear your cache and history close the browser and reboot the computer so that the next time you open the browser it will force it to open a completely new session.
Essentially, if FT works in a different browser, it's a Chrome problem. If it doesn't work on Chrome, Firefox, or IE then the problem lies elsewhere, i.e. not on your computer at all. In which case I would say what web techies always say: "it's a router". By that they mean that a computer (web server) along the route from you to FT has got a problem with its cache and needs to be rebooted. You can call your ISP about this if you like but if I know ISP techies they will say "we'll look into it, leave it with us and we'll fix it" meaning that they'll do nothing, hoping that time will solve the problem. Which it probably will as more and more users try to access FT via that router the block will clear.
