Im using a GTX gamingco control panel with uMods and i followed the steps for default config just to see how it looks in game but when i do /shop it lags for a second and then nothing happens.  no command error, no permissions issue.  is anyone able to help?

it sounds like an permission issue, make sure you have the permission granted to the correct role 

Hey Dude, press f1 and type:  oxide.grant group default guishop.use
