title: Whitenoise static file upload not working with DEBUG=False
body: <p>I have a Django web app and I serve static files with Whitenoise. The problem is that I can't upload and get images when <code>DEBUG=False</code>. Everything work well with <code>DEBUG=True</code> but when I disable it, uploading is not working anymore but retrieving images works.</p>
  
  <p>Here is my whitenoise configuration :</p>
  
  <p>wsgi.py</p>
  
  <pre><code>from whitenoise.django import DjangoWhiteNoise
  from django.core.wsgi import get_wsgi_application
  application = get_wsgi_application()
  application = DjangoWhiteNoise(application)
  </code></pre>
  
  <p>and settings.py</p>
  
  <pre><code>MEDIA_ROOT = os.path.join(BASE_DIR, 'public/static/public/images')
  STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage'
  STATIC_URL = '/static/'
  STATIC_ROOT = 'public/static/'
  </code></pre>
