Здравствуйте. Я новичок в php. Что-то изменила - теперь страница каталога, вызываемая из меню, стала просто белой без информации.

Файл index.php этой страницы выглядит так:

<?
require($_SERVER["DOCUMENT_ROOT"]."/bitrix/header.php");
$APPLICATION->SetTitle("Каталог");
?>

<?$APPLICATION->IncludeComponent(
