Can someone help?

 

I am having same problem. What plugins do you have? It could be a related problem.

 

Drop bkcommonlib

 

Update NoLagg and BKCommonLib for 1.4.7 - this is due to the version policy safeguard introduced in CraftBukkit 1.4.5, saving you from crashes and world-corruption, potentially . In fact it might have been worse without the "safeguard" in this case.

If they don't have a version for 1.4.7 you have to remove both.

(Edited: misread.)

 

Ok my server is working now. Thanks
