How do I fix my django admin page not loading css although having correct configuration?
I am aware this question has been asked a thousand times, but none of the solutions have worked for me... I was working on the Django tutorial, but when I created the superuser, and entered the admin page, the css was missing. The weird thing is, is that when I check the page source from chrome, and click one of the css references in the html, my computer manages to download the stylesheet. It only had a relative path, and when using chrome's debugger, I can see the page taking some time to download the css. So I guess the static paths are configured correctly, the page actually loads the css, but somehow it is not reflected in the view? I have no idea how such a thing can happen. Things I have tried until now: Setting STATIC_URL Setting STATIC_ROOT Setting PROJECT_DIR Setting static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) to urlpatterns Deleting static files and doing manage.py collectstatic every time i modified any files Making migrations again Adding base dir + "templates" to TEMPLATES Setting DEBUG from False to True again I must be missing something simple, but I can't see it. Any help is greatly appreciated. In settings.py: PROJECT_DIR = os.path.dirname(os.path.abspath(__file__)) STATIC_ROOT = … -
