contact-form-7 plugin upgrade to version 3.6 problem

in Additional Settings was the address of the page to transfer to when the form is filled in and it always worked until version 3.6. now it has “on_sent_ok: “location.href=” and a url but the transfer to that page is not done upon completion of the form.
