No ProgramLanguage matches the given query.
Request Method: GET
Request URL: http://he.altlibs.net/plang/kicad-schematic
Raised by: altlib.views.LanguagePageView

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

  1. [name='home']
  2. platform/<slug:slug> [name='platform-list']
  3. platform/<slug:slug>/plang/<slug:langslug> [name='platform-list-by-plang']
  4. lib/(?P<slug>[-a-zA-Z0-9_.]+) [name='lib-detail']
  5. tag/<slug:slug> [name='tag-list']
  6. plang/<slug:slug> [name='plang-list']

The current path, plang/kicad-schematic, matched the last one.

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.
