When I log in I see the Pentagrams on the left, indicating new posts in the forum. When I enter a forum, which has, for example, 5 new postings, I am transported to the last new post, but the other new, unread posts are not visible or in a different yellow.

Usually I used the "show flat" function when I missed some posts, so I did not have to click on every posting again. But this issue seems to be gone. Do I not see the option or is it really gone?

To switch to Flat Mode, just click on the "Topic Options" above the post.

Also it helps sometimes to go to the bottom of the forum and Expire your Cookie. Close your browser and re-open it again.

Seems to work now.

Thank you, Magister.
