I recently moved my site to a new host. It is not live yet, so I am working with switching the IP addresses in my hosts file to test things out. When I set the hosts file to point the IP address to host #1 and log in, everything is cool. When I set the IP address to host #2 and log in, I cannot access the admin area. However, if I login to host #1, then change the IP address in the hosts file without logging out, I can access the backend via the new nifty admin bar at the top. However, directly going to the admin pages, or trying to perform any actions in the admin area, send me to a lonely white screen. Any ideas of how to fix this?
