PDF download error after setting an invoice to "payed"

HI, I’ve installed 1.4.8 version of Invoice Plane. After recording some invoices, I’ve realized there is a problem when downloading PDF.
If the invoice is set to “Draft”, I can download it without problem, but when I change payment status from “Draft” to “Payed” and I try to download, it appears an error in a blank page, where it says invoice php file couldn’t be found.

Thanks in advance.

Have you set the PDF template for payed invoices to InvoicePlane - paid ?

Oh, thanks for your fast answer. In effect, it was that point. However, I think that for the next versions, it would be fine to automatically set a default invoice template.

I appreciate your help.

Thank you so much!
