Problem: Posts suddenly display "url='http://xxxxx'"

I run a Fantasy Football blog (http://hotfantasyfootballpicks.com) and all of a sudden my posts on the home page are displaying the full post url before displaying the post excerpt. Check out the blog to see what I mean.

Is there any way for me to fix this? It just started happening today and I hadn’t even changed anything since yesterday when it was fine.

Thanks for your help.
