Help needed

I started a server for myself and freinds to play on. While making sure everything is working I noticed that none of the modded items are able to be crafted and I couldn't find any of the modded ores while mining. I am using what I believe to be the correct jar file to run the server. It says forge-1.12.2-14.23.5.2860.jar in my files for the server
