Whitenoise Not Working when DEBUG = FALSE - Django - Hosting Static Files

[Shihab Khan]

I am running a Django website and it's about to go into production. I am now at the point where I need to set DEBUG = False in my settings.py file. I am getting the typical 500 errors because I have static files that are being hosted locally. I am working on getting Whitenoise to work to host my static files so I can move on with DEBUG = False. I have followed a lot of documentation and a lot of tutorials and think all of my configurations are all set but I am still getting the same error. When DEBUG = False I am still getting 500 errors on my production pages that have static files. Also when I inspect any static files on the page when DEBUG = True the URL has not changed at all. I am posting all of my configuration below in hopes that there is a simple mistake I made that I have been continuously skipped over but Whitenoise doesn't seem to be working and there seems to be no different from the way it was before now as Whitenoise is "implemented".
I have run python manage.py collect static
I have run pip install whitenoise
I am new to white noise so I am just basing my knowledge on the tutorials and documentation I have found.
