Hi
in my case i have the PDF-invoicefile in the History (Default List Orders) are shown when it isGerman, and in other language only someone is shown.
Whats the reason for that?
I think the reason is that the name of the invoices are translated (invoice, rechnung). So it maybe does not find the path, interesting hint.
this is possible as i use language overrides for the invoice
*EDIT*
Seems like it shows some Invoice PDFs from the language which is selected, and some are not shown at all.
