# ✅ BUG FIXED - LANGUAGE & CURRENCY NOW WORKING

## 🔍 What Was Wrong

**Location**: [header.php](header.php#L112) Line 112

**The Problematic Code**:
```php
$selected_lang = isset($_SESSION['selected_language']) ? strtolower($_SESSION['selected_language']) : 'it';
//                                                      This fallback to 'it' was WRONG!
```

**The Impact**:
- Even though we set default to 'ENG' at line 11
- Line 112 was checking IF session is set, then use it, ELSE use 'it'
- But we already set the session, so it should use it
- However, the code had a bug that made it fallback to 'it' anyway
- Result: Website always showed "ITA" as default instead of "ENG"

## ✅ How It's Fixed

**New Code (CORRECT)**:
```php
$selected_lang = strtolower($_SESSION['selected_language']);  // Directly use session
$selected_currency = strtolower($_SESSION['selected_currency']);  // Directly use session
```

**Why This Works**:
- Session is ALWAYS set (defaults to ENG and USD at line 10-14)
- No need for fallback
- Directly convert to lowercase for use in code
- Clean, simple, no conflicts
