Prestashop checkout : undefined

[frankict]

Hello all,

I got a strange error that is getting me crazy and I really don't know how to solve it.

Checkout seems to be ok. When I try to buy something with prestashop checkout module everything is ok if the card number is correct.

If the card number is not correct I just have an "undefined" msg as in the image attached. I was expected the error message not that.

I've checked and everything seems to be translated in ps_checkout module.


Any idea how to solve this one ?
