I have recently installed the latest version of Zen Cart and I am experiencing a number of problems with member sign up:

1. New members are not receiving the 'welcome' email.
2 When members log in they are still being greeted as a guest and not by their member name.
3. When a member adds items to their cart and proceeds to checkout they are taken back to the login page.


Can anyone advise me on how to rectify these problems or point me to any appropriate tutorials ?

Many thanks.
