Environment: Singleplayer / Multiplayer

Mod name: Better Beacon Placementz
Mod version: 3.1

Is this mod server or client side? For me, I watched a video that contained this mod, and a couple others such as Double Doors, and they don't work for me. I've tried them on a realm and they won't work, but they do on single player worlds. Please help.
Thanks.

The mod has to be installed on the server, since it manipulates block data. Thanks for the interest!
