Please help me!
i dont know what to do! (im new here so i dont know how to use paste bin)

 

Do you have any Plugins? Did you install these plugins correctly? What happened to cause this crash? Did you walk into a new chunk or do anything new?

 

Update a jar and see if that works.

 

Try reading the stack trace, it tells you all that info.

C0lA_K1nG "a jar"? which jar? craftbukkit.jar, essentials.jar WorldEdit.jar? the more info you give, the more it can help.

Code:

263{Essentials:com.earth2me.essentials.spawn.EssentialsSpawnPlayerListener$1@1293,Essentials:com.earth2me.essentials.EssentialsPlayerListener$1@1293,}
Profiler Position: N/A (disabled)
Vec3 Pool Size: ~~ERROR~~ NullPointerException: null

Looks like Essentials is crashing on the player spawning into the server. Try clearing your spawn points and see if that helps fix it.

 

Whoops sorry Bukkit

 

I think I have a fix for your.
I was ahving the exact same problem
It turns out it was someone spawning in the wrong world where there was no land.

Try changing HannahMae28's last login location to something that is safe.
I believe it is this that is crashing your server.

 

^ Delete her file from the world to fix it or use mcedit

 

what do u mean by walked into a new chunk??

Well the same day it happened the first time it crashed my spawn world has no grownd my spawn is floating and i went out into the fartherness of the world.... so is that the problem to fix??

so update bukkit???

 

Yes

And while your at it all your plugins
