Static Front Page Not Working Properly

Hello,

I have been running my wordpress site for a little over 2 years now and today I posted a new blog post. When I posted the new blog post, the post automatically became the front page. I tried to erase the post but now the front page is leading to an error page.

I have never had this problem before… my site address is http://www.JamelGibbs.com. Any help would be greatly appreciate.

Thanks!
