Forum Forums not updating read threads
 

Hi there, the unread posts icon on the main forum page is showing that there are unread posts when all posts have been read. If you go into the sub-forum itself, the threads are no longer in bold, meaning they appear read. But the icon on the main page shows unread posts.

I have the forum set to mark unread threads immediately.

What can I do to fix this? Sometimes it works and sometimes it doesn't. Several members have reported this now. I don't care if it takes up more resources, but what is the best way to ensure the forum/threads/posts are marked as read instantly and all the "forum-new" icon is changed back to "forum-old"?
