(VERSION 6.4.4)
Eons ago, I remember reading about people having problems with page breaks not working properly.
I've got my theme set to list 30 posts per forum topic in my "showflat" page. But when somebody posts post #31 in a topic,
it doesn't create a "Page 2" link, so that post never gets seen -- at least not
until somebody posts post #32 -- then and only then, a "Page 2" link appears.
I did a search here and at UBB/Eve/threads/infopop/WWWThreads/groupee

support forums site but haven't found a solution.
