It appears that it is a loading issue on your end, if it was server-side then it would be happening for everybody. Have you tried simply restarting your browser? If that's not working, either do as Gallows suggested or just do a full-page refresh that doesn't pull from the cache (usually something like CTRL + F5 or as you're on a Mac, probably CMD + SHIFT + R, or possibly just CMD + R)
EDIT: Just saw that you replied that it's fine.... L2reply faster Jason :l
