To enable command blocks on a FREAKHOSTING Minecraft server running Minecraft 1.21.9 or newer (including 26.x), make sure the gamerule command_blocks_work is true (it is by default). On older versions, switch on Command blocks in Server Properties and click Save and restart. To place and edit a command block, a player needs operator level 2 or higher and Creative mode.

​
Before you start

  • Know your version. The top of Version Changer shows it, for example Currently installed: Paper 26.1.1 (#29).
  • Be an operator with level 2 or higher. See how to op someone.

How to enable command blocks on Minecraft 1.21.9 and newer

In Minecraft 1.21.9 Mojang removed the enable-command-block line from server.properties and replaced it with a gamerule. Since 1.21.11 the gamerule is called command_blocks_work. It is on by default, so command blocks work unless someone turned it off.
