Well maybe thats my issue right there, I have a main.cfg in the ForgeEssentials folder, and then a FEData.h2.DB, and a Banneditems.cfg, but nothing else.
Just reinstalled Forge Essentials, at the console I added my UID to the Owners group, set the Owners group to the Default group, logged both my son and I into the game. Ran pretty far away from the spawn, to test the /spawn command, as well as /home, and from both I received
"Unknown Command. Try /help........" message
/p group Owners allow ForgeEssentials.BasicCommands.home
/p group Owners allow ForgeEssentials.BasicCommands.home.set
to make sure it was set, and still the same error message
