Comment area, links and submit not working?

Hi, I use this free version of your lovely theme. But I have one, very strange problem. When I read a single article, the comment area is "close", and so is the Submit-button, and links in the page. Also when I tried to password protect a page with WP:s standard options, the Submit-button is not working. Can you help me with this? I have unactivated all of my other plugins and tested, nothing helps. This is important, because I need this fixed before I publish my site. Thanks in advance :).
