Thx for your hard working fixing the errors that we were getting with CodeChickenCore & NEI (http://www.minecraftforum.net/forums/mapping-and-modding/minecraft-mods/1286162-biomes-o-plenty-over-75-new-biomes-plants-and-more?comment=10074)!

With the latest versions (1112 & 1113) and a newly generated Config, SP is working fine (including SP/LAN), but the Private Server MP is not working.
