Can't access anything

In the Beta Resource Pack Creator, nothing seems to work
Apart from the homepage, Dropbox page, and the Techne page, everything else is blank. Even on the dropbox page, the connect button doesn’t work, and I’m pretty sure I’m on https considering I can see http://puu.sh/fZ3or/00b01c979c.png
I’ve tried clearing my cache, and I’d rather not clear my history, but I’ve tried this on Google Chrome, Mozilla Firefox, and IE, two of which (IE & FF) don’t have any history as I’ve never used either of them, and it still doesn’t work.
I’ve never used this website before, but it seems like it’d be really useful, and I’d like to be able to use it.
Good thing the Forum works just fine.
