Debug script for OfTheDayManager issues
Run this on the Raspberry Pi to diagnose the problem

Usage:
1. Copy this file to your Raspberry Pi
2. Run: python3 debug_of_the_day.py
3. Check the output for any errors or issues

This script will help identify why the OfTheDayManager is not loading data files.
