I think you need to update your version of discourse. `ensure_all_loaded!` was recently added.

Here’s the main method that the plugin is overriding from `application_controller.rb`

```rb
  def set_locale
    I18n.locale = current_user.try(:effective_locale) || SiteSetting.default_locale
    I18n.ensure_all_loaded!
  end

```
