So I have the problem that on the checkout page when hitting the “submit form” button the following loading page is completely blank while the URL is still the same. It’s in sandbox mode and the fake credit card datas are all recognized and approved (with that little green check sign).
When I do it on my phone it doesn’t show that blank white screen but the message: This page isn’t working. http error 500.
Have already searched online but nothing found that helped
