Custom Post Type posts not displaying in edit.php
<p>My custom post type posts are not showing at all in the edit.php page in my WordPress admin site:
wp-admin/edit.php?post_type=my_custom_post_type</p>

<p>However, the page shows the correct counts for the custom post types at the top:</p>

<pre><code>All (3) | Published (2) | Draft (1)      3 items
</code></pre>

<p>The Add New link also works and I can create a new custom post type of this type, but when I save it as a draft or publish it, it does not show up in the list.  The count value will increment, as if WordPress knows the article was published, but it is not showing in the edit.php list.</p>

<p>Has anyone seen this phenomenon before?  Does anyone know what change could have caused this to happen?  It was working fine before.</p>
