 * Backend log: PHP Warning: array_push() expects parameter 1 to be array, null 
   given in /home/******/domains/******/public_html/wp-content/plugins/booster-plus-
   for-woocommerce/includes/lib/tcpdf/tcpdf.php on line 18255\n, referer: [https://www.l******/wp-admin/post.php?post=219944&action=edit](https://www.l******/wp-admin/post.php?post=219944&action=edit)
