Recent update has caused issues with fields not saving and now I receive this error
Warning: Illegal string offset ‘image_id’ in /home/customer/www/pennprinting.co.uk/public_html/wp-content/plugins/woocommerce-product-addon/templates/frontend/inputs/image.php on line 175
Yes the illegal string error is still showing error as per the link attached in my first post. The error appears when trying to add an item to the cart.
