Hey,
I tried the URL shortener.

Tried to short:
https://payments.yourpay.se/betalingsvindue_summary.php?MerchantNumber=600130338&ShopPlatform=ManualPayments&accepturl=http%3A%2F%2Ftestapp.likvido.dk%2Fdebtor%2Fpayment%2Fconfirmation%3FType%3DCreditCardFullPayment%26demandId%3D77080cf9-4cf2-45ed-98cf-d640f3e1cfe4&callbackurl=http://testapp.likvido.dk/debtor/checkout/callback&use3d=0&amount=135188,00&CurrencyCode=208&cartid=78-4346&lang=da-dk&ct=off&ccrg=0&autocapture=no

It just keeps loading. Never returns…
