I've been trying to figure this out for a couple days now and haven't been able to. I'm using the Squarebit Charge plugin to accept donations on a website.
I have everything working fine on my local Vagrant machine. However, when I push it to my staging server, the redirect to the "thank you" page never works. Instead of redirecting to the thank you page, the Donate page is reloaded and displays a single "1".
Does anyone have any ideas? I do get a TypeError in console because the card expiry date field had to be changed. Stripe would complain that the card exp_month field wasn't present so I had to create that field. I get the error on my Vagrant box too so I don't think it's causing the process to fail.
My staging link is here: kb.topsdev.net/donate
Any help is really appreciated.
