Hi @JacobCoffee ,
I'd like to request assignment to this issue. I'm building experience in Python/Django through open source contributions and this looks like a great learning opportunity.
My understanding: The admin_interface package is throwing warnings because it expects LocaleMiddleware in the MIDDLEWARE settings for its language chooser functionality. The solution would be to either add the required middleware or configure the package to disable the language chooser if internationalization isn't needed.
Thanks!
Emmanuel.
P.S I am working full time so please let me know if there is a deadline to work towards
