When setting invoice number like {$year}{$counter} I’ve got an erro that my invoice number was already set and the email can’t be sent, even if I don’t have this number in my company. Can this be a conflict with other accounts?
Now the error doesn’t repeat, it appears just under invoice #… and doesn’t give me the send email email screen… and yes, now the error is: The Invoice Number has already been taken.
I don’t know why if the number was taken I didn’t get the next number.
