In Java single-player, Open to LAN can temporarily allow commands; Bedrock uses the world Cheats setting. Turning on Bedrock cheats can affect achievements for that world.
Quick answer
Check the Java or Bedrock edition, permission level, and every command argument. Run a harmless test before changing a main world.
What to do
Work through these checks in order. Stop if a menu, command, or world state differs from the conditions described.
- Confirm your Minecraft edition and release, then identify the world, device, or server involved.
- Make a copy of the world before changing its settings.
- Open the matching edition’s world settings, enable commands or cheats, and test /help.
- Check the result in the game. If it differs, record the exact error or menu label and compare the official source for your version.
Edition and version differences
Command names, selectors, and permissions can differ between Java and Bedrock or change after an update. Custom server commands need their own documentation.
If the result differs
Compare the current screen or error text with the conditions above. Check the Java or Bedrock edition, permission level, and every command argument. Run a harmless test before changing a main world. Change one variable at a time so you can tell which step made a difference.
