Industrial Foregoing Version: 1.7.1

The block breaker and the block placer don't seem to work for me on my server. I tried the exact same setup in single player and it works...
Any idea how to fix that?

Is the area protected?

Yeah that also came in my mind just now. It works now, so nevermind.
But thanks for the quick reply ;)
