Whenever I run my local server with my django project I am getting a warning and an error message saying that in Django 1.7 the global middleware classes were changed - even
I created my project using django 1.11 but when I transferred the files to the web server, I encountered errors with fcgi which forced me to downgrade to 1.8. Therefore the error came up because admin was now expecting MIDDLEWARE_CLASSES
instead of
MIDDLEWARE.
Changing that solved the error.
