Why am I getting ValueError: Unable to configure logger 'django_request': Unable to add handler 'request_handler': 'request_handler'?

[Deanna Robertazzi]

I am making a Django site and when I run ./manage.py shell, I get this traceback:

/home/deanna/django_test/static/
Traceback (most recent call last):
  File "./manage.py", line 10, in <module>

ValueError: Unable to configure logger 'django_request': Unable to add handler 'request_handler': 'request_handler'


This is my Procfile:

web: gunicorn django_test.wsgi
I have attached manage.py and settings.py files to this post.

 I'd greatly appreciate any help you can give me. Thank you.
