Не отображается карта сайта. Как исправить?

Установила xmap, но когда захожу на мойсайт.ру/sitemap.xml вместо карты выдает ошибку:
Warning: require_once(/home/httpd/vhosts/my-psychology.info/httpdocs/includes/application.php): failed to open stream: No such file or directory in /home/httpd/vhosts/my-psychology.info/httpdocs/components/com_xmap/helpers/xmap.php on line 12 Fatal error: require_once(): Failed opening required '/home/httpd/vhosts/my-psychology.info/httpdocs/includes/application.php' (include_path='.:/usr/share/php53/pear:/usr/share/php') in /home/httpd/vhosts/my-psychology.info/httpdocs/components/com_xmap/helpers/xmap.php on line 12
