Topic: "Last post" in topic title?
When you post topic which contains "Last post" in its title, then when you go to it, it will always redirect to the last post of this topic.
Look for this topic:
http://punbb.informer.com/forums/topic/ … -lastpost/
It's not available to view first page of this topic, because it always redirect to last post. Workaround for this is removing "lastpost" from url.
