[Fixed]-Django : Getting error while removing django.contrib.sites from INSTALLED_APPS

Seems to be resolved by myself. Following things I have done to resolve it:

1. Remove following from settings.py

   SITE_ID = 1

and ‘django.contrib.sites' from the INSTALLED_APPS block

INSTALLED_APPS = [
    ‘django.contrib.sites'
]

2. Removed auto-generated files from migrations folder inside the apps (App in which I have imported django.contrib.sites Models).

3. Re-run the makemigrations and migrate command.

4. Everything is working fine.

Thanks.
