Page not found (404)

Request Method:	GET
Request URL:	http://testserver/boostrap4

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

1. ^$
2. ^django$ [name='django_rendering.views.index']
3. ^bootstrap3$ [name='bootstrap3.views.index']
4. ^bootstrap4$ [name='bootstrap4.views.index']
5. ^bootstrap4_3$ [name='bootstrap4_3.views.index']
6. ^semantic [name='semantic.views.index']

The current path, boostrap4 , 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.
