Post link is going to a different post! HELP…

http://monicadwilliams.com If you go to the link it will show the latest post, but if you click on the post beneath it “2011…” it, it will take you to the first post entitled “Monica’s moment of manfestation” Somehow, I was editing my post, and now the post link goes to a different post and shows “Archived for” at the top of the post. Please Help!
