Thanks, it works now! But i have one big issue with forum now. I always use Show unread posts since last visit to catch up with latest posts. I click on first topic with unread post(s), go to that topic, read posts, click back button to return and list with unread posts updates automatically. But since yesterday, clicking back doesn't update that list anymore and i have to update it manually. That is very very inconvenient. Was anything done to forum that could change its behaviour recently?
