Blocking a plugins command from displaying in chat and console when run from command block

I am trying to create a timer for a mini game I am working on by using a plugin called Multiple Scoreboards. The plugin basically lets you display different scoreboards to different players, so I am having it display a timer scoreboard to only the players in the minigame.

The way that I am running the timer is by subtracting 1 point every second from a player called Time_Left that is displayed on the sidebar. However, the command block that is subtracting a point every second is displaying the command it's running in both the chat of the oped players and the console.

Is there a way I can block this command from being shown to the console and oped players when it is run by a command block?

Thanks, Jonny

Solution 1:

The commands /gamerule commandBlockOutput false and /gamerule logAdminCommands false should work. The first command blocks the output from chat, and the second blocks it from logging.
