user registration

Hi,

We are currently operating the site with one free membership including one free listing package, used by default and hidden. When unregistered users click the “add your classifieds” link instead of the registration/login page they are shown the membership package and are prompted to “pay now” despite the fact that it is a free package. Clicking the link takes them to the default login page using this URL: (https://www.dogads.co.uk/wp-login.php?action=login&redirect=https://www.dogads.co.uk/add/)

Any help would be great.

Thanks, Dave
