post titles displaying vertically

For some reason, when I go into Posts – All Posts, instead of seeing the titles horizontal, they are now displaying vertically, each letter in t he title below the previous one. So that the title takes up the entire page. I created my blog page yesterday, but didn’t have any problems until today – it happened just as I was messing with disqus plug-in – not sure if the two are related. I noticed that when you hovered over the titles of each post you see Edit-Quick Edit-Trash-View options. Now I do not see those because of the orientation. Anyone have a clue why this is happening and how to stop it. I don’t think it matters but here is a link to my blog: http://fairmountpetservice.com/Blog/

Here is a link to a print screen I pasted into a word doc and uploaded to my site: http://www.fairmountpetservice.com/postproblem.doc

Hopefully you can open that, my pc or browser kept downloading it instead.

Hope someone can help and thanks!
