I am using a default_locale in my app config.i18n.default_locale = :fr
When setting up the administration part, I don't need to have a foreign locale, default :en would be fine is this error message caused by non setting the default.locale as it's stated : :locale=>[:fr, :fr]} by default ....
ActionView::MissingTemplate (Missing template admin/categories/colors, admin/base/colors, application/colors with {:handlers=>[:erb, :builder, :coffee, :haml], :formats=>[:js, :html], :locale=>[:fr, :fr]}.
