a) zencart 158

c) The one updated on 20 aug 2023

"It says "We have a problem on our end. So Sorry! Please report this error to the Store Owner: SQ-MISSING-TOKEN"

even tried this
For those wondering about 1.5.8, WebPay works exactly as expected in Zen Cart 1.5.8 WITHOUT One Page Checkout.



If you are going to use both One Page Checkout AND Square WebPay with Zen Cart, you will need to get the OLD square javascript file from includes/modules/pages/checkout_payment/ called jscript_square.php "

But did not work
