I migrated my Django app from 1.4.3 to 1.7.1
I got it working for a short while
but now every time I try to run the development server it gets stuck on:

```
C:\Users\DAVID\Documents\TinyTap-web\tinytap>python manage.py runserver
Performing system checks...

System check identified some issues:

WARNINGS:
?: (1_6.W001) Some project unittests may not execute as expected.
        HINT: Django 1.6 introduced a new default test runner. It looks like this project was        generated using Django 1.5 or earlier. You should ensure
. See https://docs.djangoproject.com/en/dev/releases/1.6/#new-test-runner for more information.

```

the localhost is not working , also tried with other IP/ports = same results.

I could get rid of this warning by adding `TEST_RUNNER = 'django.test.runner.DiscoverRunner'` to the settings file, but still development server is not running
