We use /rankup in game and it says 'cannot get group from config'. I am using Group Manager, EssentialsX and Rankup. I have spent 3 full days watching youtube videos, searching for an answer... Any advice? PS-- if you need to see in any of our files (yml), I don't know how to share them besides c&p...so if you could let me know how to do that, as well, it's greatly appreciated. Thank you SO much for your time!
