не работает переадресация на 404 страницу компонента sh404SEF. - SEF (ЧПУ)

Добрый день!

Есть кириллический домен http://этон-энерго.рф/ перестала работать 404 страница компонента sh404SEF. В панели управления sh404SEF во вкладе "ошибки 404" пусто.
Сама страница _404_ в материалах есть и опубликована. Раньше сайт был на windows сервере там все работало, сейчас переехал на Unix.
Если вводишь старый урл или неправильный выскакивает стандартная красная 404 ошибка Joomla.
Хостер уверяет что mod_rewrite у нас успешно работает. Возможно какая-либо ошибка в .htaccess.

Содержание .htaccess:

AddDefaultCharset utf-8
php_flag display_errors on
php_value error_reporting 2047
php_flag register_globals off
php_value session.save_path /home/uХХХХХХ/xn----ftbf4abdfom3ie.xn--p1ai/tmp/

# beginning of line), reload your site in your browser and test your SEF url's.  If they work,
# it has been set by your server administrator and you do not need it set here.
