[eriktelepovsky]

Can you make support for older versions, please?

Versions:
OS: Debian Wheezy
uWSGI: latest system package version: 1.2.3+dfsg-5+deb7u1

https://packages.debian.org/wheezy/uwsgi-core

Exception:

File "/home/user/environment/local/lib/python2.7/site-packages/django_uwsgi/views.py" in get_context_data
  28.             context.update(get_uwsgi_stats())

File "/home/user/environment/local/lib/python2.7/site-packages/django_uwsgi/stats.py" in get_uwsgi_stats
  39.             ('cache_exists', uwsgi.cache_exists),

Exception Type: AttributeError at /en/admin/uwsgi/
Exception Value: 'module' object has no attribute 'cache_exists'

Thank you very much in advance!
