Page not found (404)

Request Method:	GET
Request URL:	/about1/index

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

1. ^admin/
2. ^$
3. ^index/$
4. ^typography/$
5. ^about1/$
6. ^portfolio/$
7. ^blog/$
8. ^blog1/$
9. ^blog2/$
10. ^blog3/$
11. ^blog4/$
12. ^blog5/$
13. ^blog6/$
14. ^blog7/$
15. ^blog8/$
16. ^blog9/$
17. ^blog10/$
18. ^blog_one/$
19. ^contact/$
20. ^media/(?P.*)$

The current URL, about1/index, 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.
