Solution 1

It's because you have configured wsgi file incorrectly, It's should be

import os

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "kloudless.settings")
from django.core.wsgi import get_wsgi_application
from dj_static import Cling

application = Cling(get_wsgi_application())

Solution 2

I spent the day on it, and all i had to do was changing:

web: gunicorn core.wsgi --log-file=-
web: gunicorn my_app.wsgi

to

web: gunicorn core.wsgi --log-file=-

Basically removing the second line, and it worked.

    I have a simple django app that works fine on localhost (Linux Mint), but when I deploy it to Heroku I see a page with this error:

    Application Error An error occurred in the application and your page could not be served. Please try again in a few moments. If you are the application owner, check your logs for details.

    I don't really know what I'm doing here and I can't make any sense of the output from heroku logs:

    foreman start works just fine, boots up the server only if i edit the Procfile from "web: gunicorn kloudtransfer.wsgi --log-file -" to "web: gunicorn kloudless.wsgi --log-file -". my root directory is kloudtransfer, and then i have app folder, kloudless folder, and other files in kloudtransfer.
