Add this snippet of code at the top of the page to display any errors that may be thrown. Be sure to remove this code before pushing out to a production environment.
<?php error_reporting(E_ALL); ini_set('display_errors', 1); ?>
For wordpress specific sites, the following code is useful in the wp-config.php file if you are trouble shooting a live site, and don’t want to display errors to users:
if ( current_user_can( 'administrator' ) ) { define('WP_DEBUG_DISPLAY', true); ini_set('display_errors', 1); }
