Geen datums op factuur

Hallo,

Ik werk met de laatste versie van virtuemart 2.5.17

Ben bezig met de laatste loodjes. 1 van de zaken die ik nog moet fixen is dat er op 1 of andere vage reden geen order factuurdatum op de factuur word weergegeven.

Wanneer ik in de code kijk (invoice_order.php), staat er volgens mij wel dat hij dit moet laten zien.

Code:

Wat is er mis? Hoe kan ik order/factuur datum weergeven op factuur
en als er betaald is ook de betaaldatum



Met vriendelijke groet,

Geen datums op factuur
