The 'exp_month' parameter should be an integer

-- HikaShop version -- : 2.5.0
-- Joomla version -- : 3.4.3

How can I translate this pop-up window in the stripe payment form so that normal people can understand it ?

"The 'exp_month' parameter should be an integer (instead, is MM)"

It pop's-up when a customers clicks "submit payment" with out filling out credit card information.

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.
