After completing a successful transaction (my credit card was successfully billed), the following error codes were displayed at the bottom of the page:

Warning: require(__DIR__/invoice_items.php) [function.require]: failed to open stream: No such file or directory in/home/stageing/public_html/gunsgrubgear/components/com_virtuemart/views/invoice/tmpl/mail_html_pricelist.phpon line 22

I have attached a screenshot as well. Does anyone know what the issue is?

ALWAYS turn off error reporting on the server when its a love site
