Add Translations?

Hi,

the plugin is set-up and works nicely.
However for the credit card option, I would like to change the labels/placeholder text to show them in my local language.

I would like to change “Card Number”, “Expiration Date”, “MM/YY”. Loco Translate does not work. How can I do that, is there another plugin?

ps. If you want I can provide more translations for your plugin.

Regards,
