Enabling Comments

Somehow my comments were disabled, and I have no idea how they were disabled… The little check boxes weren’t messed around with in the options section, and the check boxes in my post weren’t messed around with either. They all allow comments. The link is still up in my main index page for people to comment, but everytime I click it it says “Sorry, comments are currently disabled from this post.”
I don’t know what’s up, but any help is appreciated.
