**Cause**: No reviews have been approved yet
**Solution**: 
1. Submit a review from customer dashboard
2. Approve it in admin dashboard
3. Refresh homepage

### Issue: Testimonials show "Error loading testimonials"
**Cause**: API is returning an error
**Solution**:

2. Check API directly: `api_handler.php?action=get_approved_reviews`
3. Make sure reviews table exists
4. Make sure reviews have `status = 'approved'`

### Issue: Slider not initializing
**Cause**: jQuery/Slick not loaded properly
**Solution**:
1. Check console for JavaScript errors
2. Verify jQuery is included
3. Verify Slick is included
4. Try hard refresh (Ctrl+Shift+Del then F5)

### Issue: Shows testimonials but they're blank
