					$children_data[] = array(
						'name'  => $child['name'] . ($this->config->get('config_product_count') ? ' (' . $this->model_catalog_product->getTotalProducts($filter_data) . ')' : ''),
						'href'  => $this->url->link('product/category', 'path=' . $category['category_id'] . '_' . $child['category_id'])

                }
                
  В файле /home/ohranactr/public_html/catalog/view/theme/MyTheme/template/common/header.tpl

    <?php foreach ($children as $child) { ?>
  <li><a href="<?php echo $child['href']; ?>"><?php echo $child['name']; ?></a></li>
  <?php } ?>
  
  на это:
  
                  <?php foreach ($children as $child) { ?>
                <li><a href="<?php echo $child['href']; ?>"><?php echo $child['name']; ?></a>
