I am getting a Server Error(500) when debug is set to false, But the site works fine when debug=True

At first i had an Internal server error, but that was because i did not put my SENDGRID API in my settings.py, After adding that i get SERVER ERROR(500)

This is the settings.py

EMAIL_HOST = 'smtp.sendgrid.net'
EMAIL_HOST_USER = '****'
EMAIL_HOST_PASSWORD = '****'
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_BACKEND = "sgbackend.SendGridBackend"
SENDGRID_API_KEY = "***"

ALLOWED_HOSTS = ['www.xxx.com', 'xxx.com']

MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'whitenoise.middleware.WhiteNoiseMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
 ###
 ]

     DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
    }
}

import dj_database_url

db_from_env = dj_database_url.config()
DATABASES['default'].update(db_from_env)

MEDIA_URL = '/media/'
CKEDITOR_UPLOAD_PATH = "uploads/"
CKEDITOR_IMAGE_BACKEND = "pillow"
CKEDITOR_JQUERY_URL = '//code.jquery.com/jquery-3.1.1.min.js'
STATIC_ROOT = os.path.join(PROJECT_ROOT, 'staticfiles')
STATIC_URL = '/static/'

STATICFILES_DIRS = (
    os.path.join(PROJECT_ROOT, 'static'),
)
STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage'

MEDIA_ROOT = os.path.join(PROJECT_ROOT, 'static/media')

The Static files are loaded in Debug=False

This is when i try heroku local web

 [WARN] No ENV file found
    22:19:44 web.1   |  [2017-07-29 22:19:44 +0000] [7476] [INFO] Starting gunicorn 19.7.1

I get a BAD REQUEST (400)

PS : So,some of the images are not loading too, could this be an issue with static files? But my CSS loads along with some other images.

[EDIT]The Images That are not loading are the images i upload through django's admin page when it is live. After git push heroku master the images aren't loading.

This is my wsgi.py

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "techzu.settings")

application = get_wsgi_application()

from whitenoise.django import DjangoWhiteNoise
application = DjangoWhiteNoise(application)

[EDIT : ValueError: The file 'style.css' could not be found with .]

In my case it was due to conflict between django staticfiles and django _heroku staticfiles

I had to disable one of them.

Either do this,

 ` INSTALLED_APPS={
            .
            .
            #django.contrib.staticfiles,
  }
  django_heroku.settings(locals())` #in end of settings.py

Or do this

    `INSTALLED_APPS={
            .
            .
            django.contrib.staticfiles,
      }
     django_heroku.settings(locals(),staticfiles=False)` #in end of settings.py

Or if you are using whitenoise ,disable staticfiles for both django and django_heroku.

While turning off Debugging. You need to provide ALLOWED_HOSTS in a list. Please check Django documentation for more..

Debug = False
ALLOWED_HOSTS = ['xyz.com']

Try making migrations with:

heroku run python manage.py makemigrations

heroku run python manage.py migrate

I had the same issue, but this solved it.

Added this in the settings.py 

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
        'console': {
            'class': 'logging.StreamHandler',
        },
    },
    'loggers': {
        'django': {
            'handlers': ['console'],
             'level': os.getenv('DJANGO_LOG_LEVEL', 'DEBUG'),
        },
    },
}

Got the errors in the log Apparently there was a mismatch with the names of the folders in the remote server and my local machine

You need to provide ALLOWED_HOSTS

Debug = False
ALLOWED_HOSTS = [".herokuapp.com"]

And Heroku you should use PostgreSQL

You can't use SQLite3 on Heroku. Switch to Postgres.
