GroupManager completed flopped

I recently tried /manreload, which completely broke my GroupManager. I restarted the server and got this in the console.

Code:

    ============================================================================

I checked my groups.yml, which I found to be perfectly fine. I ran it through a parser and it came out correct. Here it is anyways:

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'

When I load up my server, it seems GroupManager has appeared to be completely gone, it doesn't even show up on /plugins. I really need help, does anybody know how to fix this?

 

Code:

# missing the one at the top!
groups:
  Duke:
    default: false
and so on...

 

EliteCreeper It appears you don't have any groups in the world config, as it says in the console error:
You have no groups in plugins/GroupManager/worlds/world/groups.yml

Edit: I just noticed, You are not using Group Manager correctly, take a look at this: http://wiki.ess3.net/wiki/Group_Manager/Config

 

Just because some random online YAML parser says the syntax is correct, doesn't mean the content is correct. As Perturbee said, you're missing the "group:" line.

You can make almost all Group Manager config changes by using the in-game commands. I suggest you use them instead of editing the files, as that will prevent errors such as this.
