In settings.cfg, I set afk kick to be 'false' but I keep getting kick in my server.

If a permission node value is set to fe.commands.afk.autokick somewhere, you need to clear it.

To see that perms ar in effect on your player use "/p username perms" and browse the result to see where this node is set to true.

Try "/p global clear fe.command.afk.autokick" since "cancel" is not valid.

I use /p global cancel fe.command.afk.autokick to delete this in my global permissions. Then I check settings and already set it to false.

But I still get the AFK kick

Maybe set true on S:auto_kick in settings.cfg is opposite? ( I have no idea why I keep getting kick cause I afk)
