Django static file problem. Clicking on the files downloads

sorry for my bad english.
My index.html file cannot find the files in the static folder. When I view the page source, I click on the css file and I get different errors from time to time. Sometimes I get 404 error when I click on css link. Sometimes when I click on the css file, it downloads the file.

Django admin panel does not display correctly

Good evening, I taught the django framework at the rate.
Before that, the admin panel was displayed correctly, now for some reason it is displayed as I understood without css styles

Write, I will strip off any part of the code that you need
Please help get the old admin panel back!

From the image you posted in the comments, it does show that the files are indeed fetched and served — any 2xx code is a success so it seems like something may be going wrong on the browser it-self.
If you haven't restarted the server to apply the static files then run the cmd python manage.py collectstatic to apply the changes and see if that solves the problem.
Try also opening in a different browser, and check whether if there are any error traces under the Console tab.
Have you made any changes in the admin.py file for the .css file (e.g. changed location or altered your project structure?). If your project is version controlled you can find the error by traversing through your previous commits.

Does anyone have any ideas? It would be much appreciated.

Can you access http://localhost:8001/admin/ ?
If yes, then the issue simply is that you haven't defined a URL entry for the root http://localhost:8001/
Something like:
url(r'^$', views.index, name='index'),
should do the trick.
Don't forget to define index in views.py

Examples:
Function views
1. Add an import: from my_app import views
2. Add a URL to urlpatterns: url(r'^$', views.home, name='home')
Class-based views

Including another URLconf
1. Add an import: from blog import urls as blog_urls
2. Import the include() function: from django.conf.urls import url, include
3. Add a URL to urlpatterns: url(r'^blog/', include(blog_urls))
"""
from django.conf.urls import include, url
from django.contrib import admin
admin.autodiscover()
urlpatterns = [
url(r'^about/', include('about.urls'), name ='about'),
url(r'^', include('home.urls'), name ='index'),
url(r'^admin/', admin.site.urls),
]
Here is my first application urls.py:
from django.conf.urls import url
from django.conf import settings
from django.conf.urls.static import static
app_name = 'home'
from . import views
urlpatterns = [
url(r'^', views.index, name ='index'),
]
Here is my second applications urls.py:
from django.conf.urls import url
from django.conf import settings
from django.conf.urls.static import static
app_name = 'about'
from . import views
urlpatterns = [
url(r'^/about/$', views.about, name ='about'),
]

The order of url patterns matter. It will return any first matching pattern at the top of the list, even though there could be more specific pattern at the bottom of the list.
also a pattern like: r’^‘ will match anything. including: http://127.0.0.1:8000/abc/def/ghi/. However, normally such pattern will include another nested urlpattern, where they usually will be closed with some kind of r'^$', which match nothing more.

You need to add "about" app in your settings.py file under the INSTALLED_APPS. Like this:
INSTALLED_APPS = [
'about.apps.AboutConfig',
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'home.apps.HomeConfig',
'about',
]

Go to url.py and configure the URL like:
urlpatterns = patterns(‘’,
url(r’^$’, HomePageView.as_view(), name=‘home’),
url(r’^about/‘, include(‘blog.urls’)),
...
)
Go to settings.py and add more eventual modules:
INSTALLED_APPS = [
'about.apps.AboutConfig',
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'home.apps.HomeConfig',
'new_module',
]
