When I go into any of the forums, I used to get an orange icon in the second from left box to show posts that I haven't read.
I can't remember what it used to look like.
All I get now is an empty box.
I still see an orange icon in the main screen to show which fourms have new posts though.
What happens if you click on View Unread Posts
- top right - under the date?
I only have one unread, and the above click finds it - it has an orange icon at the beginning of the Thread Title, in the box to the right of the empty box - maybe it's slipped a bit.
