Command help

None of my commands such as /scan /upgrade /dropmoney and idk why.

You need to give us some information, such as, what gamemode are you using? What did you last do before they stopped working?

The gamemode is basewars , it never worked from the beginning.

Can you post a link to the gamemode?

My friend got this gamemode a long time ago and he fixed it up/

Then how can we help?
