correcting url error on Django 2.0

I have set up Django Ecommerce from Github that was developed with django 1.11 but I decided to implement the project on Django 2.0. As far as I am concerned, I have done the right then except the urls where I'm not very sure if I have done the right thing because its not rendering properly. I need someone who is an expert in Django 2.0 to help me correct the errors. This should take some one who knows what he is doing just a couple of minutes
