Any help is greatly appreciated

Answer 1

You're trying to access a MySQL database with the SQLite driver.

To use the MySQL driver:

pip install mysqlclient

Then in your settings.py:

DATABASES = {  
    'default': {  
        'ENGINE': 'django.db.backends.mysql',  
        'NAME': 'your_database_name',  
        'USER': 'your_database_user',  
        'PASSWORD': 'your_password',  
        'HOST': '127.0.0.1',  
        'PORT': '3306',  
    }  
}  

Also, NAME = '/var/lib/mysql/bastionblog' is wrong. You don't need to enter a path, just the database name.
