Errore ricevuta

Buon giorno. Da un paio di giorni quando vorrei creare il pdf con la ricevuta di un ordine appare il seguente messaggio di errore
“Fatal error: Uncaught exception ‘Exception’ with message ‘Template not found! Check if the following file exists:

Potete aiutarmi a risolvere il problema? Ho contattato anche l’assistenza del plugin ma mi hanno detto di rivolgermi a voi…
