Your server is a bukkit server, not vanilla.

Therefore:

This ticket is invalid as it relates to a modded or 3rd party client/server.

• Any non-standard client/server build needs to be taken up with the appropriate team, not Mojang.

• Any plugin issues need to be addressed to the plugin creator.

• This site is for addressing issues related to the base unmodded MineCraft.

I just delete "level.dat"/"level.dat_mcr"/"level.dat_old"/"session.lock"/"uid.dat" and replace theres files by others of a new world and now its work fine. When I log in my personel world, there no error. Thnx ^_

No, my server isnt modded 😉

Sure, it's a bukkit server.
