title: translation.E004) You have provided a value for the LANGUAGE_CODE setting that is not in the LANGUAGES setting
body: <p>I've just reimaged my computer, so setting everything back up for my django project, and on running the server, I get this error. I haven't a clue what it is referring to as my original site came out of the box and as I speak English and this site is an internal work site, there is no reason to do anything language based. Does anyone know what this is or how to get past it so I can carry on working? Looking in the settings file, I have this for the Internationalization section:</p>
  
  <pre><code>LANGUAGE_CODE = 'en-GB'
  
  TIME_ZONE = 'UTC'
  
  USE_I18N = True
  
  USE_L10N = True
  
  USE_TZ = True
  
  DATE_INPUT_FORMATS = [
      '%Y-%m-%d', '%m/%d/%Y', '%m/%d/%y', # '2006-10-25', '10/25/2006', '10/25/06'
      '%d %b %Y', '%d %b, %Y',            # '25 Oct 2006', '25 Oct, 2006'
      '%d %B %Y', '%d %B, %Y',            # '25 October 2006', '25 October, 2006'
  ]
  </code></pre>
  
  <p>Is this the out of the box English code? if not, could someone tell me what is should be so I can set it back please, I can't find the outofthebox settings in the documentation. </p>
