Suscription form

[elyrial1988]

In this section "Subscription Forms", I want to edit the "return url", but when I do this, nothing changes. When I update the website, and I test the "suscription form", this redirects to the old site. Because of this, I go to the "return url" option, and I see the old site, not the one I chose previously. The redirect works bad. How can I resolve this issue? Thanks in advance.
