just updated Canada Post module... even tried Dr Bites solution by just updating the canadapost.php file and clearing history... But on my Zen Cart 1.5.6c with PHP 7.2, if I simply do not update (admin)\includes\modules\product\collect_info.php, I can see my product details on the admin side but If I do, then I get this error message:

Code:

Still very early in my Zen years , learned a lot for the past three days
