When i open up the payment and fill everything out, i get this error – “Unable to load XML from remote server” and it doesn’t let me pay (right side of the payment is faded and doesn’t let me press anything on it. It was working before (few days ago when i last tried it) without any issues. Not much was changed since then, except for new payment method added, but I’ve tried disabling (removing) it again, still had same issue.
