TypeError: object() takes no parameters

This error is probably due to the changed style of middleware introduced in Django 1.10: https://docs.djangoproject.com/en/1.10/topics/http/middleware/.

The middleware class should be updated to comply with the new style.

For the moment, one can replace object to MiddlewareMixin to enable the middleware.

from django.utils.deprecation import MiddlewareMixin

class CorsPostCsrfMiddleware(MiddlewareMixin):
...

class CorsMiddleware(MiddlewareMixin):

Apparently django-cors-headers is no longer maintained, django-cors-middleware is a good alternative: https://pypi.python.org/pypi/django-cors-middleware/

Now I’ve been added as maintainer (see #110) I’ve merged Django 1.10 support, and deployed to PyPI at version 1.2.0. Enjoy.
