title: NoReverseMatch at /'blog' is not a registered namespace
body: <p>I am trying to link two pages.  Page files are home.html and pageOne.html. I am getting &quot;NoReverseMatch at /'blog' is not a registered namespace&quot;. I am using django.  When I first created the app, I named it artclBlog, I then created a templates folder and another folder within that one, this one I named blog.  I think I should have kept these two names the same, this may have caused some confusion in my code.</p>
