Why do that happend? How can I fix it? My plugins:

Code:

18:57:02 [INFO] Plugins: AuthMe, AutoMessage, AutoSave, Essentials, iConomy, Not
ificator, PermissionsEx, Residence, Vault, ChatManager, ecoCreature, ChestShop,
dynmap, LWC

Thank you!

 

Essentials always fails. @sddddgjd
No i got no idea what could cause this, which build are u using?

 

try installing Safe Creeper <- plugin(<- disables creeper explosions)
if you did: in config.yml set creeper control -> true
world destroy : false
explosion : false
(choose these yourself)

 

@MuisYa 1185, the latest. I also got the latest version of my plugins... so it's weird. I'll try to regenerate the server world later... because there are some bugs in the current world of my server... Anyway I don't think that error comes because of my world.

@ashley well yeah that's a way to avoid that, but I'd like to have creeper explosions in my server... thank you for your tip!

 

@BlancoLanda Can you please please please, backup youre essentials. Than remove it for a second to see what happens. Because it might cause the problem....

 

@BlancoLanda what plugins are you using?

 

@MuisYa OK, nice idea... I'll do that later
@ashley I posted them above in the post.

 

@ashley says in OP.
I agree with @MuisYa essentials should be destroyed in the least humane way possible. (If only to see if it is the problem) xD

 

If it's essentials' problem what should I do?

 

You should try and find a few plugins to replace its functionality. Since it probably IS the problem i would recommend you look around for standalone plugins that do what you use in essentials. I'm sure you could easily find a few plugins to work in combination to replace it

 

Leave essentials out and maybe try using CommandBook <- for craftbukkit 1060 but still works for 1185
when essentials doesn't cause the problem try using a DevBuild from Craftbukkit : ci.bukkit.org

 

I wouldn't recommend using CommandBook until it is updated. FalseBook has been updated for 1185 and it is a beautiful plugin. Maybe try a few out and see which one you like

 

HATERS BE HATIN! FUCK ESSENTIALS :<

 

@MuisYa

 

LOLLL!
Dude i was:

 

Yeah. that makes even ME seem:

So not serious

 

I tryed to remove all the plugins of my server and regenerate a new world! And this annoying error keeps happening! So it's thing of the .jar or any config of the server... can you help me?

 

If i can call you on Skype and you got TeamViewer i can. Else i cant...
