I dont have all rights... GroupManager (Essentials)

Hey i am owner on my server, but for example i can not go in the gamemode... Can anyone help me please... here are my group.yml

Code:

# Group inheritance
#
# Any inherited groups prefixed with a g: are global groups
# and are inherited from the GlobalGroups.yml.
#
# Groups without the g: prefix are groups local to this world
# and are defined in the this groups.yml file.
#
# Local group inheritances define your promotion tree when using 'manpromote/mandemote'

@Saniboy144 you can always op yourself

 

its because you have:

1. -bukkit.command.gamemode

you need to space it like this:

1. - bukkit.command.gamemode

That's causing the entire config to crash.
