First, thanks for your help.
In the orders of the list, I have an error when viewing the order:
Warning. The order must have been deleted.
When you click on the PDF icon to open the invoice, a new blank window appears.
In administrator, it works correctly.

Sorry.
VirtueMart 3.2.13
Joomla 3.8.6
PHP Version 5.6.20
url https://www.bytepc.net/tienda (page in development)
template shaper_megadeal_ii - Default
I imagine that it is a habitual error.
Any idea where to start?
Thank you.
