 * I keep getting this error no matter how I configure the plugin. It was working
   fine but all of a sudden stopped working. Any thoughts?

 * Can you please post the exact error message and where you get the error? On the
   checkout page, on the paypal page you can click on the Buy Now button, etc?

 * This is the error message, only “security check failed”
    on add to cart using
   paypal.
 * in classes / backend.php
 *  `require_once ABSPATH . ‘wp-includes/pluggable.php’; // It looks like pluggable.
   php is loaded too late, so I’ll do it
    if ( ! wp_verify_nonce($_REQUEST[‘scabn-
   add’],’add_to_cart’) ) { wp_die(‘Security Check Failed!’); }`
 * this is the code that stops it.
