Page not found (404)

Request Method: GET
Request URL: https://acadb.ru/certificates/iso-13485/Info_Moscow@acadb.ru

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

  1. [name='index']
  2. certificates/ [name='cert-list']
  3. certificates/<slug>/ [name='cert-detail']
  4. events/ [name='event-list']
  5. order/ [name='order']
  6. stati/<slug>/ [name='article-detail']
  7. stati/ [name='article-list']
  8. sitemap.xml [name='django.contrib.sitemaps.views.sitemap']
  9. admin/
  10. ckeditor/
  11. ^media/(?P<path>.*)$

The current path, certificates/iso-13485/Info_Moscow@acadb.ru, 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.
