Hello,
I have a very strange problem with ACS 3.1.1 server. Let us say if I enable in "Interface configuration\Advanced Options" almost all properties for users and groups, then when I open a user's properties page or a group's properties page some sections are just empty gray boxes. When I try to submit any changes I have a message on the Browser 's status line "Error on the page". The only work around was to deselect as many as possible properties in "Interface Configuration".
If somebody has seen similar issue, I would appreciate a lot if you could share your solution.
