Plugin Help PermissionsEX groups

My PermissionsEX is the one plugin that isn't working on my server, what is set up wrong in the permissions file?

I was also hoping someone could help me set up a helpers group and set member as the default group? How would I give players the rank/put them in the group of something like mod?

Code:

 
groups:
  default:
    options:
      rank: '1000'
      default: true
    permissions:
    - modifyworld.chat
    - essentials.afk
    - essentials.getpos
    - essentials.help
    - essentials.helpop
    - essentials.ignore
    - essentials.list
    - essentials.me
    - essentials.motd
    - essentials.msg
    - essentials.near
    - essentials.rules
    - essentials.suicide
    - essentials.clearinventory
    - essentials.spawn
    - essentials.home
    - essentials.sethome
    - essentials.delhome
    - essentials.tpa
    - essentials.tpaccept
    - essentials.tpadeny
    - essentials.warp
    - essentials.warplist
    - essentials.delhome
    - essentials.pay
    - essentials.balance
    - essentials.back

You appear to have messed up the indentation for Member,

 

What do you mean?

 

Add two spaces before "Member:"
