I got the site up on time, with one blog post up. Later I added another one and tested it. Big problem! Any link that used to take you to the old post (ie: side-bar "Recent Posts" links) now takes you to the newest one. I tested it by adding a third post, and got the same result.

This is a custom wordpress theme and I have a, page.php
