title: Can't get the templates to load in Django
body: <p><strong>This is my setting:</strong></p>
  
  <pre><code>TEMPLATES = [
      {
          'BACKEND': 'django.template.backends.django.DjangoTemplates',
          'DIRS': [],
          'APP_DIRS': True,
          'OPTIONS': {
              'context_processors': [
                  # Insert your TEMPLATE_CONTEXT_PROCESSORS here or use this
                  # list if you haven't customized them:
                  "django.contrib.auth.context_processors.auth",
                  "django.contrib.messages.context_processors.messages",
                  "django.core.context_processors.debug",
                  "django.core.context_processors.i18n",
                  "django.core.context_processors.static",
                  "django.core.context_processors.media",
                  "django.core.context_processors.request",
                  "django.core.context_processors.tz",
                  "mezzanine.conf.context_processors.settings",
                  "mezzanine.pages.context_processors.page",
                  "main.context_processors.global_settings",
              ],
              "builtins": [
                  "mezzanine.template.loader_tags",
              ],
          },
      },
  ]
  </code></pre>
  
  <p><strong>I have the structure:</strong></p>
  
  <pre><code>project_name
  - theme_1
  - theme_2
  - templates
  -- theme_1
  --- index.html
  --- base.html
  -- theme_2
  --- index.html
  --- base.html
  - static
  - project_name
  </code></pre>
  
  <p><strong>I did also try to add the structure inside the apps/themes:</strong></p>
  
  <pre><code>theme_1
  - templates
  -- theme_1
  --- base.html
  theme_2
  - templates
  -- theme_2
  --- base.html
  </code></pre>
  
  <p>What could be the issue here? Why do not my template files load? I only get the default Mezzanine project templates and static files to load.</p>
