JustTired

Whats a debug.log, because it just said that all mods are the wrong version even tho were using the same mods.

My friend and me wanted to play on a modpack, i could play perfectly, i sent my friends the mods, it went perfectly ,HOWEVER i invited my other friend and sent him the exact mods, the exact same version and also the same forge version but he still can not join and it says that the mod versions are wrong everytime he tries joining the server however we have the same as he does.
