The full error message is:
AttributeError on running Django app on apache as localhost -- \'Adminsite\' object has no attribute \'root\'
Your url for admin should be: url(r'^admin/', include(admin.site.urls)) not (r'^admin/(.*)', admin.site.root) - it's for Django 1.0. For Django 1.3 it wouldn't work.
url(r'^admin/', include(admin.site.urls))
(r'^admin/(.*)', admin.site.root)
