I am generating pdf file using below code but it give me error in log file that
FPDF error: The document is closed
$pdf = new FPDF('P', 'pt', 'Letter');
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$filename=$upload_dir["basedir"].'/borrowers/borrower'.$page->id.'.pdf';
$pdf->Cell(40,10,'fdfd');
$pdf->Output('F',$filename);
However file is being generated in the destination path but script execution stopped further.
$this->state
value need to be increased in fpdf.php as by default it is 3 which seems to be low in case document contains more than 2 pages.
