Seems I found an error where it’s loading javascript twice. Go to peoples-list.php and find and delete the line below you should be fine:
wp_enqueue_script(‘people-lists-jquery-sortable’, plugins_url(‘/people-lists/js/jquery-ui.min.js’), array(‘jquery’,’jquery-ui-tabs’,’jquery-ui-sortable’));
I’m having the same issue: here’s my link
It doesn’t print the single post ingredients list, but prints everything else.
