Modded items cant be crafted?

[Wasted_Grim]

After a while of trying to get my friends in my server we finally were all able to join. Everything was fine until I found out no one could craft modded items (ex. Buildcraft wooden gear which just takes four sticks) I’ve been reading into it and so far I’ve only see stuff about making sure the client folder in my Minecraft is the same as the server. I copy pasted it over and even checked it again after. It looks like everything is the same. I’m using the technic launcher for extra information. I’d just like to know what’s wrong. This is just something I’ve wanted to do and I keep getting so close for it to run into a problem and I’d rather not give up now. If anyone can answer this please help.

This typically means that you connected to a server without the mods installed.

I'd advise 1) Using the vanilla launcher not technic.

2) Making sure you're running the server correctly by reading the log files on the server.
