argument of type 'NoneType' is not iterable

Cloned the repo and got all the folders right, ran runserver no problems went to /facebook/connect the page comes up, the page show some of my testers photo's i click the Register, login or connect with facebook link, the window comes up i give the app permission and boom the django exception page is shown
TypeError at /facebook/connect/
argument of type 'NoneType' is not iterable

I traced it to the django_facebook/api.py line 209, somehow the sig and expected sig are not the same so it returns none and it all stops.
I tried it with another facebook account, same problem, i tried deleting the app from the facebook page and get new ID and SECRET but it also fails.
I cloned the repo today.

The current codebase is running in production without any issues. I'll have a look to see what could cause that. Do let me know if you have any leads.
