Customize Thank you page


I created a subscription page on my website.

Now I want to know how to put a “Thank you page” with the theme of my site.

Ss messages appearing on the “edit the subscribe page” it is possible to display within a page with theme on the site? . But I do not know how to insert into my site



What software is your site using? Is it wordpress?

do not. It is a theme of the SJB
