When a visitor attempts to access a page that requires a subscription or a feature level that they do not have access to view, you will want to redirect them to an Access Denied page. You can select any page or post as your Access Denied page or you may want to create a page speciﬁcally for this purpose. Your Access Denied page may be a good location to promote your subscription products. Once you decide which page you want to use, navigate to that page in your ordPress admin and add the custom ﬁeld: Name: cart66_member Value: denied
Then whenever a visitor is denied access to a page, this is the page to which they will be directed. If you are using WordPress 3.0 Menus, you probably do not want to add the Access Denied page to your navigation.
