На сервере крутится Joomla 1.5.7 c virtuemart'ом.

Значит суть проблемы в следующем, когда открываеш сайт с помощью firefox или opera и ie6  все нормально, при открытии сайта IE7  - он грузит половину контента, после чего выдает предупреждение что сайт не может быть отображени выводит страницу с разрешением проблем.
