Something just occurred to me. Did the subforum numbers change? That is, the part of my URL that had numbers in it - search.php?do=getnew&include=3,4,7,10,12,16,23,29, 39,40,43,44 - those numbers referred to specific subforums. If the subforums were re-numbered, that would explain why the search for new posts no longer works.
How can I see what numbers are assigned to each subforum. I know there was a way, because I was able to see the numbers when I put that search function together.
