Blank page shown when Jive Forum is started

Hi,

we got a blank page when the Forum is started.

Configuration of iViews is fine. Problem only occurs when forum is called when using browsers that have more security restrictions.

Strange enough the SDN forum works fine in those case, but not our own forum.

Are there ways to solve this?

Why is this blocked? Do we need java run time? Or do we have to allow scripting in the browser?

Thanks in advance.

Toine Pothuizen.
