title: Django default language
body: <p>I have a django application which has default language set to French.
  All translation strings in the code and html pages are in french. Switching between differents language works fine.
  But now I need to hide french language, so I changed LANGUAGE_CODE to 'en-us', but default page always displays in french, did I miss something ?</p>
  
  <p>Thanks</p>
