!pop is not working

@LorenzoZGX- Could you take a look at this, please?
Looks like the example configuration in documentation is blank. 

@HYPPERSWhile we wait could you delete the config file for this plugin then reload the plugin please?
I can confirm that the plugin does create a default configuration with !wipe, !wipee, and !nextwipe as preconfigured examples.

Seems to work fine here.
I suspect maybe you've had a syntax error when making your modifications?

I tested default config, to confirm it worked, then tested the following.

 

{
  "replyToEveryone": true,
  "commands": [
    {
      "command": [
        "!wipe",
        "!wipee"
      ],
      "commandResponse": "I am a test"
    },
    {
      "command": [
        "!nextwipe"
      ],
      "commandResponse": "I am a 2 test"
    },
    {
      "command": [
        "!pop"
      ],
      "commandResponse": "Test response for !pop"
    }
  ]
}

Ok,
It looks like the developer has hardcoded {players} and {queue}, both of which you can use in your config,
so you could do

 

{
  "replyToEveryone": true,
  "commands": [
    {
      "command": [
        "!wipe",
        "!wipee"
      ],
      "commandResponse": "I am a test"
    },
    {
      "command": [
        "!pop"
      ],
      "commandResponse": "There are {players} players online."
    }
  ]
}

@LorenzoZGX- This stuff really should be made clear in the description, though.
@HYPPERS - Hopefully that gets you up and running. We will be following up with the author on this, though, and removing option to purchase if necessary.
