Hai,
I am new to this plugin. For me the invoices and packing slips are working good. But, with the proforma I got this error, ” Document of type ‘proforma’ for the selected order(s) could not be generated”.
I have also tired the above code, but no use (added it in functions.php). I still get ” Document of type ‘proforma’ for the selected order(s) could not be generated”.
Could you please help solve this.
