Image cropper cart error

Hi

I’m trying to set up the image cropper on my site for a new product. During testing, I can add the item to the cart and the original and cropped image is attached and shown. But, when I view the cart page there is an error showing. Something in the functions.php file.

Warning: Illegal string offset ‘org’ in /home/customer/www/talkinghands3d.com/public_html/wp-content/plugins/woocommerce-product-addon/inc/functions.php on line 555

Here is a screenshot of it;
