I create an item shop with ServerPinging, then reload the plugin, but it shows "%players%" instead of number of player in server

Here is my item:

  SnapcraftHub:
    RewardType: playercommand
    PriceType: free
    Reward: server hub
    MenuItem:
    - type:GOLDEN_APPLE
    - amount:1
    - name:&c&l&nS&6&l&nn&e&l&na&a&l&np&b&l&nc&d&l&nr&b&l&na&a&l&nf&e&l&nt&r &6&lHub
    - lore:&7Click to connect!#&e%players% &3online
    - durability:1
    InventoryLocation: 5
    ExtraPermission: ''
    ServerPinging: mc.snapcraft.net:25565

What version of BossShop are you using?

Please provide any additional information below.
I tested with my server and others servers, but I can't get it to work.

I works with 1.6. Plugin needs to be apdated to 1.7 ping protocol
