Welcome landing not translated

Hi,

I’m trying Wysija in one site in Spanish language. When someone receives the confirmation e-mail and click the link, the landing page is in English, instead of the translated settings I’ve set in settings (second tab, “Confirmation page title” and “Confirmation page content” fields).

When I try the demo page that is in the control panel, it shows fine, but not when someone receive the e-mail, who isn’t translated.

Do you know where is the problem? thank you very much in advance.
