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

  1. [name='home']
  2. about [name='about']
  3. members [name='members']
  4. articles [name='articles']
  5. references [name='references']
  6. references/<str:mode>/<str:date1>/<str:date2>/<int:sign> [name='references_download']
  7. contact [name='contact']
  8. welcome [name='welcome']
  9. blog [name='blog_index']
  10. blog/<int:post_id> [name='blog_show']
  11. account [name='account_mypage']
  12. account/signup [name='account_signup']
  13. account/signin [name='account_signin']
  14. account/signout [name='account_signout']
  15. account/edit [name='account_edit']
  16. account/activate/<uidb64>/<token> [name='account_activate']
  17. account/password/reset [name='account_password_reset']
  18. account/reset/<uidb64>/<token> [name='account_password_reset_confirm']
  19. account/register/conference [name='register_conference']
  20. account/register/coauthor [name='register_coauthor']
  21. account/register/article [name='register_article']
  22. admin/
  23. markdownx/
  24. ^static/(?P<path>.*)$
  25. ^media/(?P<path>.*)$

The current path, GA/index.html, 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.
