Thema: Intallation von 1.7

Hallo,
wenn ich die Installation öffne kommen folgende Fehler:

Warning: ini_set() has been disabled for security reasons in /var/kunden/webs/web4782/joomla/libraries/joomla/session/session.php on line 96

Wenn ich dann trotzdem die Sprache auswähle und auf weiter gehe bleibt er hängen und es passiert nichts mehr?!
