//---> The link for viewing all / disable viewing all:
/*
<a href="<?php echo (isset($_GET['view-all']))?add_query_arg('view-all',false):add_query_arg('view-all',true); ?>" title="<?php echo (isset($_GET['view-all']))?__('View less'):__('View all'); ?>"><?php echo (isset($_GET['view-all']))?__('View less'):__('View all'); ?></a>

Moet ik hier nog wat aanpassen? Als ik deze in functions.php kopieer, krijg ik wit scherm.
