title: Internationalized Django app back to English
body: <p>My django app is in an European language. Now I want to revert back to English and do internationalization and localization properly. I did this in setting.py</p>
  
  <pre><code>LANGUAGE_CODE = 'en'
  LANGUAGES = [
      ('en', 'English'),
  ]
  </code></pre>
  
  <p>But the whole application is still not showing in English. Am I missing something here? 
  PS. The app is also using Django-CMS.</p>
