Cannot display full post (w/ any theme)

This is a weird problem, I have no idea what is causing it. Even with a default, unaltered theme (and no active plugins), I cannot get any single.php files to display.

Check out my site: http://dazestate.com/, it has the default 2011 theme up. Click on a post and you’re taken to the archives page. Click “continue reading” and nothing happens. What is wrong? I can’t get to any of my post pages. Like I said, I haven’t altered anything in the source code, and the same thing happens with every theme I install. How can I fix this?
