Hi,

On the invoice page of my test 7 words that seems te be in the dutch translation file don’t get the Dutch words, but the Enlish ones: Billing Address, Shipping Address, Invoice Number, Telephone, Product, Price and Total (once). why i can’t find…
Any help would be great!

Beside that i like to have a left alignment on the Complementaty Close text and the shopaddres needs a larger font.

Many thanks for your response.
