Zombie Mode Setup

I own a server which runs the DarkRP gamemode, and my guests would like something to legally shoot at.

I know there’s a zombiemode embedded within DarkRP, and I know the commands, but it doesn’t seem to be working.

/enablezombie turns the mode on, correct? I don’t see anything happening, I even binded “say /addzombie” to a key and went around setting spawn points … still nothing.

How are yo supposed to set zombie mode up?

Actually, I think this is in the wrong place.

Unless someone has an answer here, could this be moved to Rolepalying?
