Movable Type Mystery

For reasons that remain mysterious, the listing of recent posts from "Patell and Waterman's History of New York" (ahistoryofnewyork.com) disappeared from my sidebar after I republished some pages last night. The listing was created using the plugin Feeds.App Lite, which comes with installations of Movable Type 4. I'd been thinking of upgrading to a paid version of Feeds.App so that I can list the authors of each post, but I don't think I'll do that until I figure out what's wrong with the widget I created.

With luck or perhaps a flash of insight, I'll be able to get it working again soon. In the meantime, I'll just note that the last post concerned Herman Melville and his father's description of him as "n honest hearted double-rooted Knickerbocker."
