Page not found (404)

Request Method: GET
Request URL: http://grad39.ru/cn_programms/detail.php?ELEMENT_ID=24154

Using the URLconf defined in project.urls, Django tried these URL patterns, in this order:

  1. admin/
  2. <int:page>/

The current path, cn_programms/detail.php, 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.
