after registering on my site, the user is redirected to an empty page, only a message appears - that is says" thank-you for registering at my-site.com. 1. I would like to change this message, what file do i alter? (or) 2. I have a page delegated for the redirect, and I have chosen force menu on checkout option under hikashop config. But this redirect page does not show after registration. How do reveal this?. Which option can I use ? Please advise.

Thanks to avoid double posts:
