Configurer GlobalMarket

Bonjour,
J'utilise un plugin pour faire la boutique de mon serveur, ce plugin est Merci de vous Connecter/S'inscrire pour voir les liens.
J'utilise la dernière version de développement car les autres versions ne fonctionnent pas en 1.11
Le plugin fonctionne bien mais j'ai un gros souci pour le configurer; puisque c'est une version de développement il n'y a pas de tutoriel

Voilà ma configuration :

Code:

# GlobalMarket config: v2.0.1.37

# Persistence options. Valid options are 'flat' and 'redis' (Default: flat)
# Pointing two GlobalMarket instances at the same Redis server allows them to share data.
# If using a multi-server setup, set 'persistence.saveInterval' to zero on all but one server.
# If changed while the server is running, for example from flat to redis, GlobalMarket will /ERASE/
# the new storage method and import all loaded data into it from the previous persistance method.
persistence:
  method: flat
  redis:
    address: localhost
    port: 6379
    poolSize: 16

# closing an inventory and logging the player. (Default: 20)

# Locale files can be found and edited to your liking inside the plugin JAR.
# Be sure to migrate your edits when updating the plugin.
locale_file: en_US

# Disables the stock system entirely. Listings will function like
#  they did in previous versions, minus the mailbox. Items will
#  go straight to the player's cursor. (Default: false)
disable_stock_system: false

# How many stock slots to give each player. (Default: 16)
stock_slots: 0

# Group-based stock slot assignment. Requires a permissions plugin
#  with Vault support. This setting will be added to the default slots.

# Changing this requires a server restart

Mon premier problème c'est que les joueurs de n'importe quel groupe se retrouvent avec 0 slots dans leur stock, j'ai mis "stock_slots: 0" mais c'est parce que je veux utiliser "stock_slots_groups" mais ça ne veut pas ... Faut-il ajouter une permissions au groupe ? Ou supprimer la ligne "stock_slots" ?
Deuxième problème : Dans le stock les joueurs y peuvent stocker leurs items à vendre et achetés, mais aussi les items de leur inventaire, et utiliser leur stock comme un coffre de l'Ender portable; j'aimerais savoir si il est possible de désactiver seulement le stockage d'items de l'inventaire
Troisième problème : Où sont les permissions ? Il en manque dans celles listés sur la page bukkit du plugin

Merci pour votre aide !
