Server problem

[svoshdeman]

So i was making my own server for me and my friends to play on, but every time i make a world it makes a vanilla minecraft world. I have tried to go in the Biomes O' Plenty config and setting biomes to true and i don't know any other way. When i try after that the world just looks like this:http://imgur.com/gallery/Nb5UL0O. What i want is a world with all ores, biomes and etc. does someone have a way to fix this?

Looks like its generating in chunks on top of an old world that was partially generated. Delete the world folder, re-run the server, issue should be resolved. Also, use the launch.bat and not the minecraft server jar...
