Problem with WorldGuard or Essentials (I think :/)

Hello world! This morning, I juste watched my logs and I've got this :

I think it's a problem with WorldGuard or Essentials(no updated) and I don't like errors

Can you help me?

 

Looks more like a corrupt world.

Offline server??

 

So, there are several things happening here.

Code:

 02.02 09:43:15 [Server] SEVERE at net.minecraft.server.v1_4_R1.ChunkRegionLoader.a(ChunkRegionLoader.java:11 

Looks like a corrupted map, there are some tools that can help you to 'fix' this.

Secondly,

Code:

 02.02 09:43:13 [Server] INFO danius1022[/86.201.213.120:49411] logged in with entity id 19832098 at ([New-City] -447.5, 66.0, 672.5) 

Please 'clean' IP's and other information from logs before posting it on the interwebs, nasty people can do nasty things

Third,

Code:

 02.02 09:43:12 [Server] INFO nathan060700 issued an AuthMe command! 

Why do you use AuthMe, are you running a offline server?

 

I use AuthMe and my server is offline-mode, why? (I bought Minecraft )

And hat should I do?

It annoys me

 

Locked. If you choose to run an offline mode server you can find help elsewhere.
