Django 1.8 with Jinja2: Contrib app Admin not working

The admin app does not come with Jinja2 templates. You need to configure your project to use Django and Jinja2 templates.

The Django template docs has the following example.

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [
            '/home/html/example.com',
            '/home/html/default',
        ],
    },
    {
        'BACKEND': 'django.template.backends.jinja2.Jinja2',
        'DIRS': [
            '/home/html/jinja2',
        ],
    },
]
