Dear Python/Django expert,
Due to recent server migration, my python-powered django app throws a 500 page. The log file is listed below. Can you please give me some help in diagnosing this problem?

You need to create a 500.html template and put it in your template_dir
Template does not exist: 500.html

Django-CMS gives 'cms_toolbar_login_error' when DEBUG is False

this has been troubling me for a while and I cannot find anyone else suffering from the same problem as I am,
I've installed DjangoCMS 3.0.2 and on it, I'm trying to use cmsplugin_contact (I've done the integration and the pages load fine). It seems to work fine in debug mode, where a thank you message is shown on submission. Things go awry the moment I flip the DEBUG flag to False.
The Apache Server gives a '200 Error', which means that the request succeeded, but then something snapped. Examining the traceback in error logs, the CMS tags seem to be the culprit. Apparently, the request object is not being passed and I don't understand why.
Here's the traceback:

This problem had also arisen before, when I was not using the cmsplugin_contact module, but was resolved by setting the ALLOWED_HOSTS value and commenting out the TEMPLATE_DEBUG = DEBUG flags. Now, it doesn't seem to work. Any ideas?

500 Internal Server Error with Django 1.6 on EC2, django.wsgi

I've just finished installing (or attempting to install) Django 1.6 on an EC2 server, but I seem to be having trouble with django.wsgi.
I've installed Django 1.6, httpd, and mod_wsgi, and I'm getting the "The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, root#localhost..."
I get that I've made a misstep somewhere, but I can't seem to make out what the error logs are trying to tell me. I see there are some database errors near the bottom, and I haven't gotten to setting any up yet, but surely the errors above are from a different issue?
Here's is the latest from the error log:

Update:
Sometimes at /, I get a 404 error:
Request Method: GET
Request URL: http://ec2-54-187-46-240.us-west-2.compute.amazonaws.com/
Using the URLconf defined in joshsite.urls, Django tried these URL patterns, in this order:
^admin/
^home/ [name='home']
The current URL, , didn't match any of these.
You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.
Thank you in advance for any assistance.
But then after refreshing it sometimes goes back to a 500, almost as if chosen at random.
Check your DATABASE settings in settings.py. Looks like your ENGINE is bad. Try changing to:
'ENGINE': 'django.db.backends.mysql',
If this doesn't work, please post your database settings.

Please check my configuration setting and Let me know if I am missing something.
Thanks in Advance
You are trying to force Python 2.7 to use Python 2.6 libraries. Your django.wsgi lists the python2.6 site packages in the path, but the errors all list python2.7.
Are you using a virtualenv environment as well? Make sure you're using the python installed in that virtual environment, and not the system version - you will be missing any pip installed packages you have.
Upon further review - you don't have all of your variables defined for mod_wsgi in your VirtualHost configuration, either.

What causes Django to use 500.html only 3 out of 6 times?

This is the bizarre.
I have a 500.html template below. When I refer to a page that does not exist via the url, my 500.html will show three times (if I try to reload the page repeatedly), then I get the apache Internal Server Error three times. My broser keeps flipping between the two.
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html lang="en">
<head>
<title>Page unavailable</title>
</head>
<body>
<h1>Page unavailable</h1>
<p>Sorry, but the requested page is unavailable due to a
server hiccup.</p>
<p>Our engineers have been notified, so check back later.</p>
</body>
</html>
During the three times I get the Apache Internal Server Error, the error logs say 500.html does not exist - but it does. It pulled it up three times before.
I cleared the cache and tried a different browser with the same results.
Thanks for any help.

I would try restarting apache. I've noticed inconsistencies in how urls are handled after any change. This sounds very similar to a problem I had when a url would sometimes load on refresh.

Django OSError: [Errno 13] Permission denied: 'static'

I tried almost for a week, but could not solve this problem, and could not find anything online, that can help me.
I have a multi-domain server with Centos 5.3, and a Django project, I must deploy. I installed python 2.7 to /usr/local/python2.7 for Django 1.3 to work, also installed and enabled mod_wsgi.
Next, what I did, was checkout this project, and create virtualenv in home directory of user, who will own this application. I created wsgi script:
import os
import sys
import site
# path to domain specific virtual environment where python packages will be installed
site.addsitedir('/home/user/domain.com/project/env/lib/python2.7/site-packages')
sys.path.append('/home/user/domain.com/project/')
sys.path.append('/home/user/domain.com/project/application/')
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'
from django.core.handlers.wsgi import WSGIHandler
application = WSGIHandler()
and configured virtualhost.
<VirtualHost \
79.98.31.117:80\
>
ServerName masinis.lt
ServerAlias \
www.masinis.lt
DocumentRoot "/home/user/domain.com/"
WSGIScriptAlias / /home/user/domain.com/project/wsgi_script.wsgi
<Directory "/home/tomas/masinis.lt/liveopenly/">
Options FollowSymLinks
AllowOverride All
Order allow,deny
Allow from all
</Directory>
Alias /static/ /home/user/domain.com/project/application/static/
<Directory "/home/user/domain.com/project/application/static/">
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
What I call project, is actually a folder for virtualenv, instructions and application itself.Application in this case is django project - it has apps, settings and other stuff inside. Also it uses external applications, that are stored in virtualenv folder.
When I try to get to domain.com, I get 500 error. And error_log gives me this:

When I try to run in development mode (manage.py runserver), everything running, but it looks, like static file are not found, when accessing the page. While server log shows 302 response...
What could be the problem?
