I'm trying to make my mod multiplayer compatible, and people have said im fine with the code I have, but whenever I add my mod to the mod folder on the server, I get the following error:

 

PasteBin

You can't use client files on the server. You need to use proxies to get around this.

Do you know how to do this? Or any tutorials?

 

Thanks,
