Internal server error when commenting.

Um, just checked out your site and EVERY internal link I tried on your blog resulted in the 500 error. Not just when I tried to comment.

I have no idea why this would be happening, but I would email your host ASAP about it. They may know what the source of the problem is. Whenever I get 500 errors (never on my blog but on other sites I’ve developed, and even then a VERY rare occurance) I email my host right away and they usually sort it out for me.
