I can't place modded blocks in my modded Minecraft server. I can see my friend's hats when he wears them, but I can't place down any modded blocks. The server works, but I just can't place any blocks! I copied the config file from the mod pack to the server and I have installed forge on the server. I know the mods are the same so I don't get why I can't place any modded blocks! Please help!
