Purchase without registering problem

Purchase without registering problem

When I set "Purchase without registering" in the shop configuration. Order checkout stuck's on filling the shipping address. I fill in all fields and click Next to confirm order but clicking on Next button will only make the page with shipping address reload. When I complete order while "Purchase without registering" is disabled everything works just fine.

Anyone knows what to do?
Thanks.
