blog is all shuffled up!

I noticed yesterday that all of my sudden, my blog content is all shuffled up. The rest of my website (in the same WordPress account) is fine and unchanged– and even if you click on an individual blog entry, it’s fine. It’s just the blog page. For some reason, there are entries squeezed into the right side bar, and what I usually have there is waaaay down at the bottom to the left. My VA, who I usually depend on for this kind of issue is nowhere to be found…. and I have NO idea of what I doing…. will someone pleeeeez help????
