Hi Max,

Thank you for your youtube videos and making your materials available.

I keep running into a value error. In the Django Tutorial Part 15 I was getting the following issue: "The view accounts.views.register didn't return an HttpResponse object. It returned None instead."

I cloned this repository so I could see where I was making the mistake. The same issue occurs in the cloned repository as well.

These are the steps I take to get the error. I make migrations, then run the server. Then I go to the website and click on register, I add in the credentials (username, first name, etc.) then click submit. The website always raises: "ValueError at /account/register/"
"The view accounts.views.register didn't return an HttpResponse object. It returned None instead."

I am using windows 10.

Any help would be greatly appreciated!
Thanks,
Bradon
