Base time / automatic marked as read function suddenly strange

Hello, So far I was used to Motor-Talk, which in the forums (which I did not subscribe to or otherwise marked as..) all posts were marked as unread, which were not older than 3 days, and so I could jump directly to the first new post that there was in the topic, if I logged in, with the exception of those that I have already read. As I often fail to pass through all the forums that interest me during a visit, this was always very pr Since yesterday, however, all the topics and posts in all the forums have suddenly been marked as read since the last visit, a rather impractical matter for me. Now I have sometimes (not always…) managed to temporarily restore the old state via the Base Time function, but at the latest at the next login, sometimes even during a continuous visit, were again all posts since the last visit, whether read or not, Is it possible to permanently restore the old condition here that the function “mark as read since last visit” permanently replaces “all that is older than xx days, automatically mark as read”. Alternatively, a switch off of the function “mark as read automatically” would certainly help. Does someone have a good idea to..? with kind regards Fietser82
