PHP - Call to undefined method PDF_HTML::FPDF()..

Before one day I realize this error and I find a simple solution, See below:

On included file 'html2pdf.php' you should just rename one function name as per below:

Approx line no: 52

1. Line no: 49
Replace function PDF_HTML with function __construct

2. Line no 52
Replace $this->FPDF with parent::__construct

Enjoy!
