Can't get Stack Size Controller to work

Hi, you can tell me I can’t add the stack size controller plugin, I throw the plugin itself into the plugins folder and the config I create the text document itself and do cfg and enter it

{
  "Settings": {
    "CategoryDefaultStack": {
      "Ammunition": 10000,
      "Attire": 10000,
      "Common": 10000,
      "Component": 10000,
      "Construction": 10000,
      "Food": 10000,
      "Items": 10000,
      "Medical": 10000,
      "Misc": 10000,
      "Resources": 10000,
      "Tools": 10000,
      "Traps": 10000,
      "Weapon": 10000
    },
    "DefaultStack": 10000,
    "StackHealthItems": true
  }
}
If you had to create the configuration file manually, it's likely the plugin isn't loaded. Check your oxide/logs for errors.
