Can place/break blocks in my server

I can't place any block and break it also in multiplayer i tired edit permissions but it again doesn't work. Do you have any idea?

 

Post the Groups and Users Please

 

Code:

groups:
    Default:
        default: true
        info:
            prefix: ''
            suffix: ''
            build: true
        inheritance:
        permissions:
            - 'foo.bar'
    Moderator:
        default: false
        info:
            prefix: ''
            suffix: ''
            build: true
        inheritance:
            - Default
        permissions:
            - 'bar.foo'
    Admins:
        default: false
        info:
            prefix: '&1'
            suffix: 'Admin'
            build: true
        inheritance:
        permissions:
            - '*'

##
# Users denote which users are included in which group.
# TheNo1Yeti is in the Admin group
# Herpina is a member of the Moderator group but also has access
# to the herp.derp permissions
# Derpina is a member of the admin group but does not have access
# to the derp.derp permission node
# Users can also have a prefix and suffix as seen with Herpina

        group: Admins
        permissions:
    Herpina:
        group: Moderator
        info:
            prefix: 'Moo'
            suffix: 'Cow'
        permissions:
            - 'herp.derp'
    Derpina:
        group: Admins
        permissions:
            - '-derp.derp'

 

/facepalm. Set up a real groups.yml with nodes and users correctly with the nodes of the plugins you have. Don't use the example setup.

 

Wow.
