Problem found in creating an account in virtuemart

[The Godfather]

Hi

When you want to create an account in website, if you forget to check ( Click here to read terms of service and check the box to accept them. ), a white page will be appeared with a check box. For example, i wanted to create an account ( http://awesomescreenshot.com/0345qkq743 ) I just left ( click here to read terms ... ) unchecked, when i clicked on register, just a white page like this appears: ( http://awesomescreenshot.com/0cc5qkq819 ).

In all other sites,when someone forget to check ( accept terms of services), the page refreshes and shows an error to check ( accept terms of services). P.S: All input wanted remains, I mean there's no need to fill first name, last name, address and so on.

That rules out a VirtueMart problem, so it is obviously an issue with your commercial template. I suggest you ask the template developers about the problem.  http://forum.virtuemart.net/index.php?topic=108212.0
