Hey guys,
I'm having trouble with those command blocks, they are enabled in my server and I checked with F3, but when I tried use them ( clicking with the right-button) they don't open. I've tried reset my server several times but the problem still persists 
Thanks!
Stop your Server. Wait a Minute. Enable Commandblock. Wait a Minute. Start the Server
Make sure you are Operator on your server and in Creative game mode, while clicking the command block.
