Hi,
Thank you for the help 🙂 it was most helpful… when I understood the problem, I knew what to do… I was focusing on the card and not on “cash on delivery”, and when I chose the delivery service that I wanted to use it didn’t work, so maybe even I tried it 😀 who knows 😀 … When I chose some other option, it worked and also I found that I used demo card mode… so that was another problem…

I asked the support for the plugin of delivery if there is not some problem on their side.
But when they say that everything is OK on their side, I will be back 🙂

thanks
