Beginning with WP 3.1, the categories on all my subsites will not pull up the posts linked to the categories. Categories will pull up pages but not posts
I am using the Twenty-Ten theme.
To see the problem, go to http://fvcctrustees.com/
and click on some categories on the sidebar. It takes you to a search window which works fine. Notice how the footers below the posts indicate the categories.
Thanks for any ideas,
