I'm trying to start a modded forge server to play with friends, installed the server client, did everything with the minecraft .jar file to create the server files, created a mods folder and placed the mod in it. The problem is: The mod doesn't work in multiplayer... works fine in singleplayer but in a server I can't do anything with the custom items.
Mod and forge-1.12.2-14.23.3.2676-universal:

If you need something just ask!
Thanks in advance. Portugal40
