 * Hi! After the update to version 12.0.3 I get those PHP Warnings:
    `PHP Warning:
   Undefined array key 1 in /.../wp-content/plugins/woo-product-feed-pro/classes/
   class-get-products.php on line 4938`
 * Can you please help me fix that?

   I will close this topic for housekeeping reasons now.
