You can only enable hardcore Mode or Questing mod ingame

/hqm quest
/hqm hardcore

I suggest to give us a ingame disable funktion because i dont know how i can disabled now hardcore mode (wrongly enabled on the Server)

Ok i delete the config and restart the Server that works for me now but a option ingame would be better,

I dont think you need to delete it, just change the config, theres an option in there for enabling the mode and you can just change it to false.

@suprememiners
sure you do it this way too but than you have to shutdown the Server and kick all Players.
It would be easy more to have a ingame option.
@lorddusk
Not sure why the Modmakers not answering to implement this or not.
When i typing hqm they give the available commands but this looks like this.

your server doesn't understand < and >. $e is < and $f is >.

At the time there is no way to disable hardcore or questing mode when enabled.

Is there any chance to implement this in future Version or not?

maybe.
