I had a query to display a certain category of posts on a parent page, sorted by expiration date. It was working fine until I recently updated Post Expirator, then it stopped working.
The method I was using was the following:
$args = array(...'meta_key' => 'expiration-date', 'orderby' => 'meta_value');
The query returned nothing unless I took those meta_key/orderby args out.
Please advise. Thanks.
