I figured it out myself — suppose I shoulda wrestled with the code a bit before I posted…
Anyway, if anyone else has this problem, I replaced this code in line 442 of wp-blog-header.php…
$where .= ' AND (post_status = "publish"';
…with…
$where .= " AND (post_status = 'publish'";
I know nothing about PHP — this is the first I’ve ever worked with it — so I don’t know what exactly this does… But I do know everything’s workin’ as it should be…
