Does anyone have experience using a Subrion-powered website? I'm enjoying my online home, but I can't get any of the comment plugins to work. So far, I've tried Comments, Wall, and Guestbook, with no success. In theory, installing and activating a plugin from Subrion is basically a two-click process, yet I always wind up getting an error message if I test one. My sister also tried to comment, with the same results.
