I have been using the Square payment form since 2018. Yesterday the form has stopped working. You can add your information but when you try to add credit card information the fields will not take information. link to payment form: www.yoursnap.org/index.php/online-rental-payments
I'm having the exact same problem. I have updated Joom Donation to the latest version and installed the Squareup Card plugin. I'm still not able to process a payment. I get a "The requested page can't be found." when trying to process a donation.
