title: How to add russian language support to Django CMS?
body: <p>I've installed Django CMS following guide <a href="http://docs.django-cms.org/en/latest/introduction/01-install.html" rel="nofollow noreferrer">http://docs.django-cms.org/en/latest/introduction/01-install.html</a>, but see only english language in interface.</p>
  
  <p>I've looked at docs <a href="http://docs.django-cms.org/en/latest/reference/configuration.html#i18n-l10n-reference" rel="nofollow noreferrer">http://docs.django-cms.org/en/latest/reference/configuration.html#i18n-l10n-reference</a>, added <code>ru</code> to <code>LANGUAGES</code> and <code>CMS_LANGUAGES</code> variables in <code>settings.py</code>, russian language appeared in interface selector, but when I select it, it goes back to english and shows <code>"[15/Feb/2019 15:06:19] "GET /ru/ HTTP/1.0" 302 0"</code> in log.</p>
  
  <p>Here is language related parts of my <code>settings.py</code>:</p>
  
  <pre><code>...
  LANGUAGE_CODE = 'ru'
  ...
  LANGUAGES = (
      ## Customize this
      ('en', gettext('en')),
      ('ru', gettext('ru'))
  )
  
  CMS_LANGUAGES = {
      ## Customize this
      1: [
          {
              'code': 'en',
              'name': gettext('en'),
              'redirect_on_fallback': True,
              'public': True,
              'hide_untranslated': False,
          },
          { 
              'code': 'ru',
              'name': gettext('ru'),
              'fallbacks': ['en'],
              'public': True,
          },
      ],
      'default': {
          'redirect_on_fallback': True,
          'public': True,
          'hide_untranslated': False,
      },
  }
  ...
  </code></pre>
  
  <p>Could anybody help me to translate my Django CMS installation?</p>
