Hi, I use Attachserial to send gift voucher to buyer, and I see that description field of the product display the html tags, like <p>description text</p>.
Is there a way to correctly display the HTML fields, or remove these HTML TAGS, with strip_tags or with script?

I need to have one serial generate by product, regardless of the quantity purchased, is it possible?
Thank you,

Thank you, line 438 in attachserial.php I have replaced

$d['text']);

strip_tags($d['text']));
