Hi,
The error is not an error provided by our plugin but by Stripe itself.
If you want to see to translate it ; you should put your own JS code in the "stripe_end" view (using a manual view override) and perform a manual "translation" of the text before his display ; or contact Stripe.
alert(response.error.message);
$form.find(".payment-errors").text(response.error.message);
