Strange error Django 1.9 "runserver" command not working in one of my virtualenvs

I started having problems recently with one of my apps. It started after running command "runserver" a few times but now It doesn't start at all.

I have not idea what could be wrong.
Edit:
I've already tried:
Recreating manage.py file from scratch.
Reinstalling django with pip.
Recreating the virtualenv.
The error disappears when removing this line :
url(r'^admin/', include(admin.site.urls)),
From my urls.py , however this is not a solution since a require to use the admin on my app.
Edit
This behavior seems to happen only when using django 1.9 , django 1.8 works flawlessly. I assume the error could be related to a failing third party app.

AttributeError: 'module' object has no attribute 'META' in Django Project

I am working on a blog in Python-Django. When I run the command "python manage.py runserver" in my project folder, I get following error:
Traceback (most recent call last):
File "manage.py", line 6, in <module>
server = request.META.get('wsgi.file_wrapper', None)
AttributeError: 'module' object has no attribute 'META'
I have not seen this error anywhere. Should I include Meta class in my installed_apps? How do I do it?
Here is my manage.py:

This is really a big code bulder.
This piece of code here makes no sense inside the manage.py
from django.http import request
server = request.META.get('wsgi.file_wrapper', None)
if server is not None and server.__module__ == 'django.core.servers.basehttp':
print('inside dev')
Perhaps you copied it from somewhere, and didn't put it where it belongs.
This piece of coude would belong in a view. It will never work inside manage.py, and makes asolutely no sense there.
[EDIT]
ALSO, in a view, you should NOT include the import, or you'll get the same error. That means, don't include this from django.http import request

Django VariableDoesNotExist exception on Eclipse PyDev when rendering template

I just started a new Django project. At the moment I haven't written any code, just some tweaks on the settings file. I am using eclipse with PyDev and when I debug the app with eclipse, whenever I try to access to http://localhost:8000/admin the debugger catches a VariableDoesNotExist exception. If I resume the debugger, the page loads properly.
I've tried running ./manage.py runserver, and then the page loads fine. It is also working on heroku.
This is a screenshot from Eclipse at the moment that the debugger stops:
I've been using Eclipse with pyDev for other Django projects and never had this problem before.
This is how my settings/base.py looks like:

I've also tried with the default value for TEMPLATE_CONTEXT_PROCESSORS.
Thank you.

How I fix it:
On the caught Exception view, right-click on the exception and then 'Ignore ...'
On PyDev > Manage Exception Breakpoints uncheck Suspend on django template render exception and make sure you don't have any of the checkboxes on the list selected.
Probably only 2 is needed, but this is what I did.

Django AUTHENTICATION_BACKENDS import error

What is the proper way to import a custom backend in settings.py? I currently have the following in settings.py:
AUTHENTICATION_BACKENDS = ('apps.apployment_site.auth.CustomAuth')
where apployment_site is the app, auth is file name, and CustomAuth is the class name.
In my view, I get: ImportError: a doesn't look like a module path after I run the following code:
from django.contrib.auth import authenticate
from apployment_site import *
authenticate(username="username", password="password")
Here's my full settings.py:

make sure it's a tuple:

note the comma at the end

I don't think you need to actually import it into your view. According to the documentation, Django will go through all your authentication backends when you call authenticate().
Thus, just make sure you have all the authentication backends you want in your settings.py.

Static files in django 1.5 - working locally, not working on Heroku

I have a project in Django 1.5 and hosts it on Heroku.
The problem is that I do not see the server static files (CSS, JS) (on the user and administrator) - went through the tutorial available at: https://devcenter.heroku.com/articles/django-assets
but nothing helps.
When I start the application locally using python manage.py runserver - everything works. Below is the code from the file setting.py

I think you need to change your setting for Heroku so that you include

Its using a different lookup to
