[Answered ]-How do I debug a production server not finding settings and logging files not working?

Your logging is configured to log only critical messages. You might want to use logging.critical instead of logging.debug as a short term approach, or lower the level of messages to be logged, using level=logging.DEBUG in the configuration.

Also, logging.* methods use root-level logger. You might want to add granularity by providing more loggers in the configuration and using something like

logger = logging.getLogger(logger_name) #logger name is often just __name__
logger.debug(whatever)

Refer to logging documentation for details.
