Ошибка при использовании Ajax ScriptManager

Здравствуйте! У меня возникла проблема с использовании Ajax ScriptManager. Я его применил в чате. На моем IIS все нормально работает, никаких проблем. Но вот когда я его залил на хостинге, то выходит следующая ошибка:

SCRIPT5022: ASP.NET Ajax client-side framework failed to load SCRIPT5009: "Sys" не определено

Уже пересмотрел все что можно и ни где толкового рецепта не нашел для решения данной проблемы. Может кто либо сталкивался с данной ситуацией.

Вот содержание web.config:
