How to properly enable mptt_url?

Question

Django

The site uses MPTT.
Example from urls.py

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^(?P<path>.*)',
        mptt_urls.view(model=Page, view=views.page_view, slug_field='slug'),
        {}, name='page'),
]

It was written to do so in the docks to mptt_url, but if I go to the address - admin - then I get a 404 error. And if - admin/ - then everything is in order. And so with each page, if you write without a slash, then 404. And if everything is in order. APPEND_SLASH = True in settings. How to fix this error?
