title: Django: TemplateSyntaxError: Could not parse the remainder
body: <p>I am getting this issue when I type <code>localhost:8000/admin/</code>.</p>
  
  <blockquote>
    <p>`TemplateSyntaxError: Could not parse the remainder: ':password_change' from 'admin:password_change'. The syntax of 'url' changed in Django 1.5, see the docs.</p>
  </blockquote>
  
  <p>Here's part of my <code>settings.py</code>:</p>
  
  <pre><code>INSTALLED_APPS = (
      'django.contrib.auth',
      'django.contrib.contenttypes',
      'django.contrib.sessions',
      'django.contrib.sites',
      'django.contrib.messages',
      'django.contrib.staticfiles',
      'grappelli',
      'filebrowser',
      # Uncomment the next line to enable the admin:
       'django.contrib.admin',
      # Uncomment the next line to enable admin documentation:
      #'django.contrib.admindocs',
       'tinymce',
       'sorl.thumbnail',
       'south',
       'django_facebook',
       'djcelery',
       'devserver',
       'main',
  )
  AUTH_USER_MODEL = 'django_facebook.FacebookCustomUser'
  
  AUTHENTICATION_BACKENDS = (
      'django_facebook.auth_backends.FacebookBackend', 
      'django.contrib.auth.backends.ModelBackend',
      # Uncomment the following to make Django tests pass:
      'django.contrib.auth.backends.ModelBackend',
  )
  </code></pre>
  
  <p>Did I do anything wrong?</p>
  
  <p>PS: This is my full traceback
