Register and Pay doesn't work anymore

[Logickske]

Hi,

I've updated a VM2 website to a VM3 website.. Now I'm trying to make a testorder but I'm not able to finish the order. I still get that register form and doesn't get any further in the process..

This is the website: http://joomla3.gittesjewels.be.

Just try to do an order..

Thank you in advance for the help!

Kind regards
