Hi,
In the theme language settings, it seems there’s only a post-submit message if someone has NOT subscribed to our mailing list.
But when a subscribed e-mail tries to sign up again, the page refreshes and does nothing and does not give an error message like “You have already subscribed!”
How can I add a “You have already subscribed!” post-message if someone tries to re-subscribe?
I am using the sense theme.
