I have a topic that now has 58 replies, some of the replies are rather long. The links (in the Recent Forum Replies widget) to any replies after the 55th reply are sent to an empty reply form. It seems that those links point to a “future” page. In other words if there are 4 pages of replies, any replies after 55 point to page 5.
I have tried changing the number of replies per page and also a number of the forum repairs under Tools but nothing seems to fix it.
