Final update:

I uninstalled the plugin and reinstalled it. I activated it.

The offending post appeared on my Blogs page.

I then edited

wp-hide-post.php

from

/**
 *
 * @return unknown_type
 */
function wphp_is_front_page() {
	return is_front_page();
}

to

/**
 *
 * @return unknown_type
 */
function wphp_is_front_page() {
	return is_front_page() || is_home();
}

Problem solved!

I forgot I had deactivated the plugin. I re-activated it, and now it works.

So, I have no idea whether it was the code tweak above or the deactivation / reactivation that fixed the problem.
