It's as the title says. I'm attempted to edit the php file that builds the invoice pdf used to print out the order details of a purchase (www.morroccomethod.com/order-history/num...3?order_pass=p_9f3b6). However, what I want to change can't be found in the details_order.php because it only shows up on the pdf file (www.morroccomethod.com/index.php?option=...er_number=9a13033793).

What I want to change, is to remove the "Morrocco Method" header and subheader (but not the image header), since it's redundant. The file that builds the pdf for the invoice (components/com_virtuemart/views/invoice.php) is written a bit out of the level of my expertise. Is there a way to remove just those two headers from the generated pdf file?

I do not think you need to make any changes in the codes to achieve this. You can control/customize the PDF invoice format right from your VirtueMart Shop settings area under Invoice tab.
