Помогите решить проблему

сперва в .htacess добавить RewriteRule ^sitemap.xml$ index.php?route=information/sitemap/xml [L]
ну а дальше в контроллер catalog/controller/information/sitemap.php добавить:

Код:

public function xml() {
        if ($this->config->get('sitemap_pro_status')) {
            $output  = '<?xml version="1.0" encoding="UTF-8"?>';
            $output .= '<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:image="http://www.google.com/schemas/sitemap-image/1.1">';

            $this->load->model('feed/sitemap_pro');
            $this->load->model('tool/image');

            $products = $this->model_feed_sitemap_pro->getProducts();
            
                $output .= '<url>';
                $output .= '<loc>' . 'http://bambook-store.ru/' . '</loc>';
                $output .= '<changefreq>weekly</changefreq>';
                $output .= '<priority>1.0</priority>';
                $output .= '</url>';

            foreach ($products as $product) {
                if ($product['image']) {
                    $output .= '<url>';
                    $output .= '<loc>' . $this->url->link('product/product', 'product_id=' . $product['product_id']) . '</loc>';
