New users can’t register; maybe someone recognizes these errors?

Basically what it amounts to is new users can’t register for my site: http://bitcoininspace.com. (Maybe somebody here could try it and let me know what they get, and maybe walk me through some steps to fix it. All I get is that Javascript and cookies need to be enabled even when I’m sure they’re both enabled. I tried both Firefox and Chrome and neither work.) I suppose I could do it manually, but that gets annoying and could scare off new users if they can’t register on their own.
