I’m sorry but there is an error somewhere:

```plaintext
Started GET "/" for x.x.x.x at 2015-11-19 13:44:56 +0000
Processing by CategoriesController#index as HTML
Completed 500 Internal Server Error in 3ms (ActiveRecord: 0.0ms)
NoMethodError (undefined method `ensure_all_loaded!' for I18n:Module)
/var/www/discourse/plugins/variable-language/plugin.rb:35:in `set_locale'

```

I added the plugin in the container configuration file:

```plaintext
hooks:
  after_code:
    - exec:
        cd: $home/plugins
        cmd:
          - mkdir -p plugins
          - git clone https://github.com/discourse/docker_manager.git
          - git clone https://github.com/scossar/variable-language.git

```

… and rebuilt the container. Afterwards, I received a 500 (see log above).

May you have a look at that, please?
