Try adding the following to your MIDDLEWARE_CLASSES setting:
'django.middleware.common.CommonMiddleware',
This middleware tries to find a flatpage for any 404.
Alternatively add this catch-all url pattern at the end of your url
patterns sequence:
(r'', include('django.conf.urls.flatfiles')),
Note that the admin > flatpage URL entry should have leading and
trailing slashes, as per the instructions. By default, flatfiles use
the 'flatfiles/default' template, but this is customisable in the
admin > flatpage 'advanced' subsection.
Hope that helps,
Kieran
