The activation link received in the email sent to new sign ups does not take the customer to the newsletter subscription activation page, instead they land on the shop home page "Default.aspx" with no welcome message and they don't get registered as active in the nop_Newsletter table. The problem seems to be that the link in the email points to myStoreURL/Default.aspx/newslettersubscriptionactivation.aspx. This should be myStoreURL/newslettersubscriptionactivation.aspx.
How can I change the link in the email sent to the customer when they sign up for newsletters?
