as I see that server colobration is enabled on server.
the only thing you have to make sue is that Client settings of that particular document.
Open that document in deskop client
then go settings -->Document properties --> Server Tab -->
in qlik view server collobration area check allow server bookmarks
then save the document and now try to acess the document and make book marks.
this must solve your problem
Note:- client settings over ride server settings.
so you have to enable on both client and as well as server, Inorder to allow that feature working.
