Django admin page appears to be blank - django-admin

Question

I wondered if someone could help me resolve as to why my admin page appears to be blank? I am able to log in successfully with my superuser. For example when I go to localhost:8000/admin/ -the page returns with a login form, then when I click 'login' the resulting page is blank. I have already checked that 'django.contrib.admin' is installed in every URLS file. I have registered the models in the django admin.py files. I have also reinstalled Django.
