Error All Group Manager Commands Locked

So I tried making another rank straight up from typing it in the config and then I saved it but when i reloaded the server I couldn't use the command anymore. I deleted the legendary rank and then it still said it please help.

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'
