I'm still using CW 2.0.20 and just recently I'm having problem with the checkout. When I try to exit the cart by clicking on the pay-button, I get this message:
"Processen misslyckades. Uppdatera sidan och försök igen."
In english: "Process failed. Update the page and try again."
First I thought this was related to PayPal as paying option, so I deactivated that. And now only has check (renamed as invoice). But the problem remains.
Very happy for any help.
