Hello,
I a number of 1.8.2 servers and on only one the unread posts don't display on the site or course Front Page. The forum tracking is turned on both for the Admin/forum activity and the user account(s). Could the issue be the theme? Is it a permission thing? The number of replies and unread display properly once you open the individual forum.
Thanks
Alan
Check in the User profile, the setting "Forum Tracking" and set it to "Yes: Highlight new posts for me"
