I posted a new topic,
and I can see it in the block "New forum topics",
Click the "forum" link at the left sidebar navigation, and it returns the basic informations about the forum; I can see "Topics 1, Posts 1, Last post: 6 hours 42 min ago by admin".

But when I click the specific forum name, it returns no topics.
