I have no idea how to disable the channels on a server.
To the people who say that it is boring to play without a channel, my base in Stoneblock 2 is too big and the channels are simply not enough.
In the AppliedEnergistics2.cfg under config> AppliedEnergistics2
Line 142: B: Channels = true
Change true to false, save, start. Make a backup of your world because everything related to channels will be removed.
Where can I find it?
Stoneblock2 folder
Config folder
AppliedEnergistigs2 folder
On the server or in your own settings
Where you want to deactivate it.
Then where do I have to look at the server use Aternos
In the Config folder under AppliedEnergistics2 is AppliedEnergistics2.cfg, you open this with a text editor and change the line. I can't tell you where that is at Aternos.
