Помогите с выводом каталога

Как у вас выглядит урл страницы раздела?

up 1

<?
include_once($_SERVER['DOCUMENT_ROOT'].'/bitrix/modules/main/include/urlrewrite.php');
if(file_exists($_SERVER['DOCUMENT_ROOT'].'/404.php'))
include_once($_SERVER['DOCUMENT_ROOT'].'/404.php');
?>

Извиняюсь наверное это вот этот:
<?
$arUrlRewrite = array(
array(
"CONDITION" => "#^/articles/([0-9]+)/#",
"RULE" => "ELEMENT_ID=$1",
"ID" => "",
"PATH" => "/articles/article.php",
),
array(
"CONDITION" => "#^/stock/([0-9]+).html#",
"RULE" => "ELEMENT_ID=$1",
"ID" => "",
"PATH" => "/stock/stock.php",
),
array(
"CONDITION" => "#^/news/([0-9]+).html#",
"RULE" => "ELEMENT_ID=$1",
"ID" => "",
"PATH" => "/news/details.php",
),
array(
"CONDITION" => "#^/catalog/([0-9]+)/#",
"RULE" => "SECTION_ID=$1",
"ID" => "",
"PATH" => "/catalog/index.php",
),
array(
"CONDITION" => "#^/catalog/([0-9]+).html#",
"RULE" => "ELEMENT_ID=$1",
"ID" => "",
"PATH" => "/catalog/details.php",
),
array(
"CONDITION" => "#^/portfolio/([0-9]+).html#",
"RULE" => "ELEMENT_ID=$1",
"ID" => "",
"PATH" => "/portfolio/work.php",
),
);

?>

Нет, urlrewrite.php у вас правильный. Не знаю, в чём может быть дело.
Сделайте показ $_REQUEST["SECTION_ID"] в /catalog/index.php. ID раздела выводится правильно?

Хм.
Покажите содержимое файла /catalog/index.php

Вот весь /catalog/index.php

А вот эти компоненты "bitrix:catalog.filter" и "bitrix:catalog.section" они отключины на странице

Вот блин на картинки news.list2.png я в поле свойства поменял с ([SIZE] Размер) на (Область применения) и всё теперь страница каталог продукции просто пропала пустая, чё делать я в панике        

Поменять обратно. Пример настройки у вас перед глазами; исходный код страницы вы тоже запостили.

Вы имеете введу вот сюда прописать где я отметил на картинке?

Ну слава богу вроде заработало. Спасибо Вам огромное
