Redirects requests that are not prefixed with a language segment to the right content in the default language. Also, if a URL is encountered that has a language prefix when it shouldn't, it will remove it.

TAKE NOTE: This middleware shouldn't even be necessary, and in fact, when I rearranged my projects middleware, the need for this functionality disappeared as it is already done in other middleware.

I added middleware in my project root and when i added in
MIDDLEWARE_CLASSES

so url
127.0.0.1:8000/fr/

works perfectly

but when i changed language to english

127.0.0.1:8000/en/

so it gives

"Page not found (404)"
Eror

In my settings.py

LANGUAGE_CODE = 'fr'

how can l solve this
Pls help,
Thanks in Advanced!!!
