## 🐛 Troubleshooting

### Issue: Sidebar not showing on desktop
**Solution**: Check CSS media queries. Sidebar should be visible by default on screens > 1024px.

### Issue: Data not loading in sidebar
**Solution**: 
1. Check browser console for errors
2. Verify API endpoint is accessible
3. Ensure database tables exist (reservations, service_reservations)
4. Check database connection in config/database.php

### Issue: Real-time updates not working
**Solution**:
1. Verify JavaScript console for errors
2. Check if setInterval is running
3. Confirm API endpoints return data
4. Check network tab in DevTools for API calls

### Issue: Responsive design broken on mobile
**Solution**:
1. Clear browser cache
2. Check viewport meta tag exists
3. Test in private/incognito window
4. Try different mobile browser

### Issue: Sidebar overlay doesn't close on mobile
**Solution**:
1. Ensure click handler is attached to nav links
2. Check if sidebar has 'open' class
3. Verify CSS z-index is correct

## 🚀 Performance Optimization

### Current Implementation
- **API Calls**: 2 per refresh cycle (room + service reservations)
- **Refresh Rate**: 30 seconds (configurable)
- **Database Queries**: LIMIT 50 per table (optimized)
- **Network**: Minimal payload, JSON format
- **Rendering**: Virtual DOM updates only changed elements

### Optimization Tips
1. **Increase Refresh Interval**: Change 30000ms to 60000ms for less frequent updates
2. **Reduce Items**: Change LIMIT 50 to LIMIT 20 for fewer database rows
3. **Lazy Load**: Load data only when tab is active
4. **Caching**: Cache API responses between refresh cycles
