Hi,
I re-installed the latest version from today.
Now I have a new and very strange problem:
When changing the ORDER to "confirmed" I do not get the error message anymore.
An pdf is opened automatically in a browser window with the name "index.php-1.pdf",
when trying it a second time there is a pdf named "index.php-2.pdf"... and so on.
This pdf has 10 pages with some information in it, but of course it does not look as the voucher should look like.
No email with the PDF voucher is sent to the customer.
With QR Code or not, changing pdf template.... - always the same problem.
