But, after updating the Django version to 1.9 in the project's virtual environment, we got the following error:

{{{
raise AppRegistryNotReady(""Apps aren't loaded yet."")
django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.
}}}
We have many installed apps in the project and using PostgreSQL-9.5 database. We know that the apps which have model classes in it, cause this error to occur.
The above error even occured when connecting to the database using connection cursor: 

{{{
django.db.connection.cursor().execute()
}}}
