I am currently having an issue when I run the command /lp group editor - It just displayed the luckperms version with nothing else. I have used LuckPerms on a vanilla server so I am familiar with how it works overall.

SpongeForge Version 1.12.2-2768-7.1.5
LuckPerms Version 4.3.75

Any help would be greatly appreciated!

Just noticed there was an issue between LuckPerms and another Sponge Plugin. Removing the plugin has granted me the ability to use the /editor. Please set this to solved/remove it if need be.

Also make sure you update. Your version is fairly outdated.

And if that message appears it means you don't have permissions.
