CodeCallback_PlayerCommand(args) does not work

[IzNoGoD]

You are giving very little information to begin with

All you're basically saying is: i painted the fence red and the dog doesnt like it.

This doesnt give us information about
1) wether or not your dog can see colors
2) if the paint is still wet
3) if the paint still smells
4) if there's a bear behind the fence which the dog might be afraid of
5) anything vacuum-cleaner related

To translate the above into your question, could you confirm that
1) you have libcod installed properly
2) which version of libcod you have installed
3) does your libcod version match your cod version
4) which mods you are running
5) what script files are inside those mods
6) what error your server crashes with
etcetera.
