sudo systemctl status redis
sudo systemctl start redis

# Test connection
redis-cli ping  # Should return PONG

# Check Redis memory usage
redis-cli info memory

Google OAuth Issues

# Verify OAuth configuration
- Check GOOGLE_CLIENT_ID and GOOGLE_CLIENT_SECRET
- Verify callback URL matches Google Console settings
- Ensure domain is authorized in Google Console
- Check redirect URIs configuration

File Upload Issues

# Check upload directory permissions
ls -la /path/to/upload/directory
chmod 755 /path/to/upload/directory
chown www-data:www-data /path/to/upload/directory
