Hi Daniel, Thanks for your reply. The settings seem to be fine I think: DATABASE_ENGINE = 'mysql' # 'postgresql', 'mysql', 'sqlite3' or 'ado_mssql'. DATABASE_NAME = 'testdb' # Or path to database file if using sqlite3. DATABASE_USER = 'root' # Not used with sqlite3. DATABASE_PASSWORD = '' # Not used with sqlite3. DATABASE_HOST = '' # Set to empty string for localhost. Not used with sqlite3. DATABASE_PORT = '' # Set to empty string for default. Not used with sqlite3. I've never come across that error before. And this code used to work when I run it some months ago... I'm really at a loss here.
