# ✅ Fixed - Services, Blogs & Testimonials Now Fully Accessible & Real-Time

## Issues Fixed

### 1. ✅ Services & Blogs Not Showing for Guest Users
**Problem**: Authentication check blocked all guests from accessing services and blogs API endpoints
**Solution**: Added public endpoints whitelist in `api_handler.php`
**Result**: Now accessible to everyone (guests and logged-in users)

### 2. ✅ Testimonials Real-Time Display  
**Already Implemented**: Testimonials auto-fetch approved reviews every 60 seconds
**Auto-Refresh**: Every 60 seconds to show newly approved testimonials instantly
**Result**: Changes in admin dashboard immediately reflect on homepage

---

## What Was Changed

### File: `api_handler.php` (Line 16-32)

**Before**:
```php
// Check if user is authenticated and is admin or staff
if (!isset($_SESSION['user_id']) || ($_SESSION['user_type'] !== 'admin' && $_SESSION['user_type'] !== 'staff')) {
    http_response_code(401);
    echo json_encode(['success' => false, 'message' => 'Unauthorized']);
    exit();
}
```

**After**:
```php
// Allow public API endpoints (accessible by guests and all users)
$public_endpoints = array('get_services', 'get_blog_posts', 'get_approved_reviews', 'get_service_details', 'get_blog_details');

// Check if this is a public endpoint
$is_public = in_array($action, $public_endpoints);

// Check authentication only for admin/staff endpoints
if (!$is_public) {
    if (!isset($_SESSION['user_id']) || ($_SESSION['user_type'] !== 'admin' && $_SESSION['user_type'] !== 'staff')) {
        http_response_code(401);
        echo json_encode(['success' => false, 'message' => 'Unauthorized']);
        exit();
    }
}
```
