Comments panel won't open

Hi guys,

This morning I noticed I can't open the comments panel under a video when I simply click on it. I can however, open it in a new tab. It does seem to fully function in that new tab, but I'm sure that's not as intended.

Browser: Google Chrome

OS: Ubuntu 12.10

EDIT: Appearantly it shouldn't appear when I click on it, as the comments section should be there by default. Swapping between the video tab and the comments tab didn't do anything. Also I should note that I thought this wasn't posted, since I got an Error 500 when clicking submit. Checking the forums later on a different PC (Windows 7, Chrome) made me realise it did get posted after all.

The comments section isn't showing up on anything including the podcast page's and text articles. Opening them in new tab's doesn't help me either.
