Maybe you can't change the number of threads displayed on the page. I thought you could. I am showing 25 threads per page.

EDIT: I think I may have figured out something that you guys have maybe done accidentally. Click USER CP at the top left then scroll down to EDIT OPTIONS. Click it. Then on the right scroll down to the section that says THREAD DISPLAY OPTIONS. The fourth section down in there it says DEFAULT THREAD AGE CUT OFF. What does your box have selected? I would guess at show threads for the last day, 2 days or week. If so, then change it to SHOW ALL THREADS.

If it already says that then I am not sure what is wrong. Let me know if that works.
