将作者电子邮件地址附加到paypal的产品 - 代码已停止工作

Question

The following code has been working beautifully for my Woocommerce Wordpress website, but after the most recent update it has stopped working.

Anyone have any insight into what may be causing the code to stop working?

Any insight or help will be such big help as this is a key feature of my site.

Thanks!
