With New Blog Templates. How can I redirect user to the site/create page?

when visitor is clicking on theme preview "select this theme" he gets automatically redirected to subscriptions page. As a result logged-in user is not able to create a new site. Instead he gets a message: "Your current subscriptions are listed here. You can renew, cancel or upgrade your subscriptions by using the forms below". I would like to redirect him to site/create page. How can I do that?
Thank you
