I am unable to get Target Audiences to work on Sharepoint 2010. The "Target Audiences" textbox is grayed out, and none of my Sharepoint Groups are searchable via the Search window that opens by clicking on the "Browse" button next to the textbox.
On a different site on the same server, I have imported a 2007 site. Target Audiences works just fine on that site, UNTIL I switch the UI from v3 to v4.
Any ideas on what's going on?
