[Fixed]-Bitnami Django Stack admin site does not work

Sorry i am late to the party, anyway the error is from your database.
It seems you have not created the core user table yet.

you need to run the following command as soon as you create your django project and setup your database:

python manage.py migrate

This will create the django core tables
it is only after this, that you can create a superuser

now run the following code to create a super user account and follow the prompts to create a username and password.

python manage.py createsuperuser

Note that, if you dont migrate the core tables first you will get an error about table auth_user not found.
