flask render_template returning blank page/empty response

Question

I am programming a relatively straight forward web application in Flask. I have used flask for about a year now, and have never had this issue before.

In my '/create_user' function, the render_template response is always blank (even when I use the more explicit make_response function).

Here is the relevant view & jinja2 template: https://gist.github.com/ianseyer/848332cea6f7ef1f69c2

Strange!

extending macros.html was failing silently. Removing the extension solved the problem.
