Apache and mod_wsgi WSGIDaemonProcess config error - django

Question

I'm having a lot of difficulty with apache(Apache/2.4.7 (Ubuntu 14.04)) and mod_wsgi and my django site. My configuration has been working for a long time, then I'm not sure what I did (possibly because I moved the virtualenv, and didn't reflect this accurately in the config, or possibly just a server upgrade, I'm not sure), but now I get errors like
#/var/log/apache2/error.log

#/srv/apache/log/mysite_error.log

I tried reinstalling and re-enabling mod_wsgi:
sudo aptitude install libapache2-mod-wsgi
a2enmod wsgi
service apache2 restart
and this did not help.
My wsgi file for django looks like:
#/srv/apache/mysite.com_wsgi.py (perms are www-data.www-data 644 on file, 755 dir above)
#!/usr/bin/env python
settings_module = "settings"
os.environ["DJANGO_SETTINGS_MODULE"] = settings_module
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
and my apache conf looks like:
#/etc/apache2/sites-enabled/mysite.com.conf:
<VirtualHost *:80>
# Admin email, Server Name (domain name), and any aliases
ServerAdmin me#gmail.com
ServerName www.mysite.com
ServerAlias mysite.com
WSGIScriptAlias / /srv/apache/mysite.com_wsgi.py
# Log file locations
LogLevel info

<Directory "/srv/www/mysite.com/static">

</Directory>
</VirtualHost>
Some dir structure notes:
The django site files are at /srv/mysite which is djangoUser.djangoUser 755 (and all files/dirs below are owned by djangoUser too). The virtual env is at /srv/mysite/venv and again all owned by djangoUser with same perms pip install gave them. Other files inside /srv/mysite/ are also owned by djangoUser with dir 500, files 400.
The wsgi file is at /srv/apache and it and the apache dir are www-data.www-data with the wsgi file 644 and dir above 755.
The static files are at /srv/www/mysite.com/static with everything owned by www-data, and dir .....I can actually access say the favico or robots file without problem...www.mysite.com/favicon.ico shows it without error.
Has anyone got any ideas what the problem could be? I thought at first it must be permissions, but I cannot see any issues.
Finally /etc/passwd shows the djangoUser as
djangoUser:x:999:999::/home/djangoUser:/bin/false
