Help with GM Commands!?

Hi all Im the GM for Insane shaiya, and i have a few things that im unsure of as far as some of the GM commands. Here goes:

1. /aban - /bancan or anything like that typed in it kicks me from the server
2. /pvpoff - /pvpon it kicks me from the server
3. etc.....

I would like to know if anyone has found a solution to the problem, and if so, if you don't mind sharing with me on how to fix that, it would be a great help.

Thanks GM INSANE

think /aban has to be followed by a name perhaps the pvp one does too just a theory try it out
