Custom user authentication for GAE project

Question

I am trying to use this webapp2-user-accounts project for custom user authentication for my project files using the Google Analytics Embed API project. Essentially I want to combine the working functions of each project into a single project - I can get each project to work individually but can't get them to work together!

I have updated handlers on my app.yaml to combine both projects (possibly where I might be going wrong). This is below:

# For production:
application: ga-dev-tools

# For staging:
# application: google.com:ga-dev-tools

version: v9-1-3
runtime: python27
api_version: 1
threadsafe: yes

handlers:
- url: /favicon\.ico
  static_files: favicon.ico
  upload: favicon\.ico
  secure: always
- url: /public
  static_dir: public
  secure: always

#my webapp2-user-accounts-handlers.
- url: /signup
  script: main.app
  secure: always
- url: /login
  script: main.app
  secure: always
- url: /forgot
  script: main.app
  secure: always  
  #my ga-dev-tools-handlers.
- url: /server-side-authorization/
  script: lib.app.router
  secure: always
- url: .*
  script: main.app

 libraries:
- name: webapp2
  version: "2.5.2"
- name: jinja2
  version: "2.6"
- name: yaml
  version: "3.10"
- name: pycrypto
  version: "2.6"

  skip_files:
- ^node_modules

I have also got my main.py file to point to a new location for the authenticated file.

However, after deploying to appspot my login page works as expected but after logging-in. My 'secured' page throws the following Internal Server Error message:

Traceback (most recent call last):

If anyone can point me in the general direction of where I might be going wrong I would be very grateful.

Thank you in advance.

This was resolved by changing the config settings for the django templates as suggested by Tim Hoffman. It was not a app.yaml issue (as I had previously thought).
