Ok I know that someone has mentioned this but I need to get their attention. How can I setup a quick temp world that will work now. Even if plugins dont work. I just need players to log in :/
Backup your existing server. Download minecraft_server.jar from minecraft.net. Run the minecraft_server.jar in a different directory than your main CB server. The result is a freshly generated world with fresh config files.
I think you can just rename your world folder to something other than world, and your server will create a new one next to it. To revert just flip the names around again.
