I have a problem with notifications and unread posts. The links from the powdered (whether in an e-mail or on the forum) often direct to posts that I have already read in a given topic. I get a notification that a new answer has appeared in the subject and after clicking it directs me to the old post. For example, the subject has 20 pages, after clicking I am directed to the last but one post on page 17, and this post I read in this topic 2 hours ago.
Any idea about the cause and how to improve it? Forum settings or the problem is somewhere else?
