I'm with this problem - [Object error] - when I try to list the Apps using the link "List all Documents". If I use the option below (Open with QlikView Analyser), I can reach the Apps list and open the qvw without any problem. I'm thinking that my problem is with the IIS, because the QlikView Server is working normally.
Environment: QlikView Server 8.5, IIS 7, Windows Server 2008.
Have you tried to change the authentication method on IIS ? I'm having the same problem then i change the authentication method on IIS (under Directory Security) after that no more "object error" and all the document list is appear again.
