I upgraded my blog at http://artlung.com/blog/ and now all my old posts (over 2000) are invisible. New posts show up fine. I can see the counts of posts in the admin, and my related posts plugin for individual posts shows post titles currently hidden http://artlung.com/blog/2007/01/22/wordpress-21-ate-my-blog/ - but in linking through, i get not found, and they are not visible in admin.
i suspect the db upgrade hiccupped maybe? how do i force the db changes again?
php4, mysql
