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

1. admin/
2. [name='index']
3. category-listing/ [name='prolisting']
4. products-category/<str:pk>/ [name='productscat']
5. products-details/<str:pk>/ [name='productdetail']
6. about-us/ [name='aboutus']
7. infrastructure/ [name='infrastructure']
8. clients/ [name='clients']

19. contact-us/ [name='contactus']
20. ^images/(?P<path>.*)$
21. ^static/(?P<path>.*)$

The current path, products-category/3/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.
