Invalid argument supplied for foreach()

  • Hey!
    I installed the Plugin and it seems to be very, very great!
    I am beginner developer of wordpress
    It works so far but also causes a PHP Error. This is, showing error where ever i used that fields says:
    “PHP Warning: Invalid argument supplied for foreach() in
    public_html/wp-content/plugins/woocommerce-poor-guys-swiss-knife/classes/woocommerce-poor-guys-swiss-knife.php on line 7915
    But when i try to find out that line number code it was not there.
    Can you please suggest me that how can i solve this.
