# SEO Tools Page White Screen Fix

## Problem
The SEO Tools admin page (`admin/controller/seo_tools.php`) was showing a white screen.

## Root Causes
1. **Missing $user variable**: The `sidebar.view.php` requires a `$user` variable to display the username, but it wasn't being set in the controller
2. **Duplicate header inclusion**: The controller was including `header.view.php` directly, but `sidebar.php` (included by `seo_tools.view.php`) also includes the header, causing conflicts

## Solution Applied
Updated `admin/controller/seo_tools.php`:

1. Added user information retrieval before including views:
```php
// Get user information for sidebar
$user = get_user_information($connect);
$user = $user[0];
```

2. Removed duplicate header inclusion:
```php
// Before (WRONG):
require '../views/header.view.php';
require '../views/seo_tools.view.php';
require '../views/footer.view.php';

// After (CORRECT):
require '../views/seo_tools.view.php';
require '../views/footer.view.php';
```

## How It Works Now
- `seo_tools.view.php` includes `sidebar.php`
- `sidebar.php` includes `header.view.php` and `sidebar.view.php`
- Both have access to `$connect` and `$user` variables
- No duplicate inclusions
- Page loads correctly

## Testing
Access: `http://localhost/alone/admin/controller/seo_tools.php`

The page should now display:
- Sitemap statistics (URLs, posts, stores, coupons)
- Generate Sitemap button
- Submit to Search Engines button
- robots.txt editor
- Full admin sidebar navigation

## Files Modified
- `admin/controller/seo_tools.php`
