When I open the forum in the node tree in ACP, this 29 is the number displayed in the URL next to the forum name. But in the actual forum, the threads are still arranged in descending order of last post date and not the first post date.
Still nothing happens to the title. That is, there is no addition of the number 29. So I'm afraid it is not recognizing the correct forum? But when I open the forum in node tree in ACP, 29 is the number that is displayed!
