I have a customer who originally choose to pay by cash COD and decided afterwards he wanted to pay by credit card in installments.
In Shopify app, in my order, i chose “Collect Payment” then instead of choosing “Mark as paid” i chose “send an invoice” (pay by credit card opens up but does not give the customer chance to pay in installments).
Customer now receives an invoice with a blue “pay Now” button, which, brings me an error page “There was a problem loading this website”
I somehow am missing something in the configuration of my checkout or payment option but do not what to do to fix.
Can anyone help?
