Works flawlessly here... Either it has already been fixed or maybe you're on a slow internet connection? I notice the top bar with the login info loads last.
OR you're in a country that blocks facebook? I noticed problems arising in China most likely due to the "login with facebook" button that doesn't load properly (and the rest of the login section with it)

(note: this was on the old website. haven't tried it on the new one actually)
