I'm guessing some issues might be with the update creating 2 world files on the servers..
When I updated mine, I ftp'd to it to see what the judgment settings were and discovered 2 world.xml files.
World_1.xml
World_2.xml
World_2 is my normal one, which was setup via my host,
the world_1 was a default file.
So I downloaded both, edited the new world_1 to match what my server information is (found in world_2). **Make sure you get the <ID></ID> correct**
Deleted both files from server (which was still shutdown)
uploaded new world file, as "World_2" which is what mine was originally named.
And it works fine..
