Very strange command probleme

[ship_killer6666]

I download everything for a GARRY'S MOD 10 dedicated server

I can start it with hostname, maxplayers, rcon password, gamemodes, the maps

but if I try any console command that start with "SBOX" (ex sbox_maxprop 200), it give me "unknow command"

I tried to put these commands into server.cfg, and autoexec.cfg

don't work either, I need them, because people can't spawn prop, they can't do anything withtout prop and sbox_ ... command

please help

Please go to the manufacturers website and ask for support there, I have no idea how this mod works nor how it communicates with the server.
