Dashboard disappeared

I have been trying to move my site chitchatmagazine.com to another hosting site and have run into a problem. I ftp all files over and changed the config file to the new hosting co. info. but I did not realize I had to change the URL via the Dashboard – Setting area (the url is different). I transferred the site back to my hosting company and had some issues but eventually it came back up but the look is all messed up and when I try to access the admin editor to get the Dashboard to display a blank screen comes up.

Can someone let me know what files need to be fixed with old backup copies.

Thanks so much.
