I have a page that should display as a PDF using the WKHTMLTOPDF mechanism. When I click the link to load the page, I get this error:
WKHTMLTOPDF didn&
The stack trace is as follows:
APP \ Plugin \ CakePdf \ Pdf \ CakePdf.php line 234 → WkHtmlToPdfEngine-> output ()
} } $output = $Engine->output();
APP \ Plugin \ CakePdf \ View \ PdfView.php line 97 → CakePdf-> output (line)
prints this
$ this-> response-> download ($ this-> GetFileName ()); }
$this->Blocks->set('content', $this->renderer()->output($content)); return $this->Blocks->get('content');
then prints the page exactly the way I want it too.
