Can't post comments in new Jezebel layout.

I was able to post comments/ responses to comments on the original "here's the new commenting system" post, but now I can't respond or post comments in any other posts in the new layout! The comment box that pops open when I click on the "respond" arrow doesn't have the links for adding an image or a YouTube video like they did earlier today. So I put my plain-text comment in there and hit submit and NOTHING HAPPENS. It just sits there. Help!
