   - Verify file permissions (755 for PHP)
   - Verify .htaccess rules still work

3. **Database Verification**
   - Verify consultations table has `updated_at` column
   - Verify status ENUM has all values: pending, approved, declined, scheduled, completed, cancelled
   - Run: `DESCRIBE consultations;`

4. **Test Polling API**
   - Access `/api/get-consultation-status.php` directly
   - Should require authentication
   - Should return valid JSON

5. **Test Customer Dashboard**
   - Login as customer
   - View consultations
   - Check status badges display
   - Check browser console for errors

6. **Test Admin Approval**
   - Login as admin
   - Find consultation to approve
   - Click approve button
   - Check database status changed

7. **Test Real-Time Update**
   - Open customer dashboard in Window 1
   - Open admin dashboard in Window 2
   - Admin approves consultation
   - Watch Window 1 for update within 5 seconds

8. **Monitor Logs**
   - Check Apache error logs
   - Check PHP error logs
