Alright, no matter what website, what topic I look at, I can't find any reason behind why my forge won't allow me to use certain mods that my buddies can use and put on a multiplayer server they can join. Some examples are Fairy Lamps and Master Chef. No matter what I do, what suggestions I try out, it seems like nothing works. The mods have been installed in the mods folder of my .minecraft folder. They are all 1.11.2, the current forge update I have, and forge's server and client are the same number. Even uninstalling Forge itself has made no difference. I didn't name the files, named the files, and I'm officially all out of ideas.
Please, I need to know if someone can help me figure out what I'm doing wrong.
