Hi !
No you do not need to setup any thing in admin options .
When you have any error in registration form then user is redirected to error page which shows the error in detail . if everything is ok then it redirects the user to reg_complete.asp , other than these pages it should not redirect users to any other page . if you have modified the scripts then send ftp info at support@mailyoulike.com we will fix any error in the scripts due to modifications
Thanks
