Error (or bug) on order payment step

[clarissa]

Hi all,

 

I'm still configuring my site and I have a problem on order payment step.

 

When clicking "Next" buttom on "Shipping" step page (after choosing carrier and agreed with Terms of Service), I'm taken to a non existent page instead of the page on which there should be the payment methods to be choosen.

The message chosen is: "Sorry, but the Web address you entered is no longer available."

In that page it is also showed the product search box.

 

I understand this is a bug and ask for your urgent help.

 

I have Prestashop 1.5.3.1 version and a non default theme.

 

Thanks in advance.
