an internal error occurred....

hello i got my minecraft server and everytime i try to make a command with factions like /f create (name) or /f help and more then it just says: an internal error occurred while attempting to perform this command? how to fix this ?

 

error log would help.

 

An internal error occurred message likely means that there's something wrong with the plugin, and probably not your server. Someone correct me if I'm wrong.

 

Code:

thats the code of my console

 

Which version of faction and mcore you are using?

And you're using Bukkit-1.6.4-R2.0?

 

no my minecraft is 1.7.4 and i can join my server so i think its craft bukkit 1.7.2 wait ill try to install the newest one

still dont work.. :i

 

Shouldn't you be using this version?
http://dev.bukkit.org/bukkit-plugins/factions/files/64-factions-2-3-0-mcore-7-0-x/

 

thats the one iam using i mean that the one iam using is the verision for 1.7.2 craftbukkit

wait it works now!

 

The version for 1.7.2 bukkit should be 2.3.0 not 1.7.4_dev
