I have a Hermitpack server on which I have installed plugins like adminshop which uses signs in order to buy/sell stuff. Now in the serverconfig I disbaled the editing of signs but sadly this doesnt work. Is there a way for you to implement a config for server to disable editable signs? Or am I just doing something wrong in the config and is it possible to disable it?

PLugins like griefprevention do not block users from editing signs sadly.

Updating to the newest version of Sponge has seemed to fix this for me.
Cheers!
