Content saving but not appearing

Ive been building templates and suddenly hit a point where no content added in the admin appears on the page. It saves fine, but doesn't show. If I use perch_content and then choose the template, there's no problem. But when I use this instead

<?php 
    perch_content_create('Header', array(
        'template' => '/case-studies/cs-header.html',
        'edit-mode' => 'listdetail'
    ));
?>

...the template doesn't render at all, but appears to save no problem. Note, this was working fine earlier but now has stopped. Im working on my localhost and have deleted and re added regions/templates several times and stopped/restarted MAMP.
