Domain is not mapping properly

I've been having the hardest time getting my url, betaverse.org, to work after upgrading my AWS stack.

my homepage is now:
http://ec2-107-20-151-52.compute-1.amazonaws.com/

and I need to link it back to betaverse.org. I think all my DNS stuff is right, but I believe I have a plugin issue. Possibly in the sunrise file.
