Hi guys,
Thanks for your help. I did check the validation message in a Dutch version of Chrome and it appears that hatesspam is right. The messages are translated in the browser’s language. They do not appear in the pot file mollie-forms-nl_NL.po.
But I stll didn’t find how to translate the payment status rendered by the {rfmp=”status”} variable in my e-mails. There are 2 payment strings in the pot file (Paid and Not paid) but they do not seem to work for the mails.
