If you are using an older version of LimitedCommands, you will need to delete your config for this to work!
The Group Support Update
Hi, LimitedCommands-ers! Today, we're updating the plugin to now support different command groups! That's right, no more big list of commands for everyone. Now you can create individual groups with their own permission nodes and accessible commands.
To learn the new config, please refer to the main resource page. If you have any issues or questions, message me on discord at MisterPorkchops#0160
