Hello, Jan
I have done as you said but there are no errors
Maybe the problem is not described well
When it generate the invoice in pdf format you can only see the header "company name and logo." .
In the body does not see anything, the page is blank
At the bottom you see the additional information.
Why do not you see anything?
I found another error. In ivoice page menu when you click on "edit order" I get this error
"Fatal error: Class 'ps_product' not found in / web / htdocs /
www.fatelettronica.it / home / administrator / components / com_virtuemart / classes / shipping / whip.php on line 69"
This is due to the use of a module for calculating the cost of shipping it, but I had already worked with the previous version
