The default behavior for most Minecraft servers is to disable command blocks. Command blocks are a special block only placable by operators, this block can run Minecraft commands when a redstone signal is received. This can be used to automate certain tasks, create gamemodes or challenges within the server. Command blocks are also required for many custom worlds.

Warning: Enabling command blocks can open your server to lag or potential abuse by operators.
