Login: 500 Internal Error

I was attempting to redirect my homepage to my blog and changed the link in my backend settings > general.

I simply changed the homepage link from http://www.blakevic.com to http://www.blakevic.com/blog-2. I now have a 500 Internal Server Error if I try to log into my backend.

I have no idea how to access my dashboard and correct this problem.

Any help is welcomed. Thanks!
