OK. IT WORKS.
I disabled native VM invoices support by going to VirtueMart -> Configuration ->Checkout -> Default Order Status to send an invoice -> set to empty.
THANK YOU.

Hello.

When I change the order status to confirmed, select the option "Notify Customer" and I click on Update, shows the following error:

Fatal error: Call to undefined method MYPDF :: SetDefaultMonospacedFont () in / homepages/26/d433978098/htdocs/guist/components/com_virtuemart/controllers/invoice.php on line 155

Help please.

My server can upload up to 2 MB. That's not the problem. Please, I need a solution.
