## ✨ KEY CHANGES IN DETAIL

### JavaScript Changes (header.php)
**Old:**
```javascript
function changeLanguage() {  // No parameter
    const langSelect = document.getElementById('languageSelect');
    const apiUrl = window.location.origin + (...) // Complex URL building
```

**New:**
```javascript
function changeLanguage(selectElement) {  // Accepts parameter
    const langSelect = selectElement || document.getElementById('languageSelect');
    const apiUrl = '/emporio-sport/api_set_preference.php';  // Direct URL
    // ... bulletproof error handling ...
```

### Favicon Changes  
**Old:**
```html
<link rel="icon" href="/sport-pics/logo-1.png" type="image/png">
```

**New:**
```html
<link rel="icon" href="/sport-pics/logo-1.png?v=<?php echo time(); ?>" type="image/png">
```

### Image Path Changes
**Old Function Would:**
- Input: `"pics_ecom/p1.jpg"`
- Output: `/emporio-sport/ecoms/pics_ecom/pics_ecom/p1.jpg` ❌ WRONG

**New Function Does:**
- Input: `"pics_ecom/p1.jpg"`
- Detects: Contains `pics_ecom/`
- Output: `/emporio-sport/ecoms/pics_ecom/p1.jpg` ✓ CORRECT

   ```

   ```
   Ctrl+Shift+Delete → Clear All → OK
   ```

   ```
   F12 → Console tab → Look for red error text
   ```

5. **Take a screenshot of:**
   - The error message (if there is one)
   - The URL bar (to confirm correct URL)
