    Use ob_end_clean(); before calling $dompdf->stream();.

    yes this is an problem of dompdf. But I am able to overcome from this problem. I created a function for pdf creation. check below function:-

    function pdf_create($html, $filename='', $stream=TRUE) 
{
    require_once("dompdf/dompdf_config.inc.php");
    $savein = 'uploads/policy_doc/';
    $dompdf = new DOMPDF();
    $dompdf->load_html($html);
    $dompdf->render();
    $canvas = $dompdf->get_canvas();
    $font = Font_Metrics::get_font("arial", "normal","12px");

    // the same call as in my previous example
    $canvas->page_text(540, 773, "Page {PAGE_NUM} of {PAGE_COUNT}",
                   $font, 6, array(0,0,0));

    $pdf = $dompdf->output();      // gets the PDF as a string

    file_put_contents($savein.str_replace("/","-",$filename), $pdf);    // save the pdf file on server
    unset($html);
    unset($dompdf); 

}

    Note :- You need to get generated pdf as string then save it to pdf file.

    EDIT :- You may delete the below part from above function:-

        $canvas = $dompdf->get_canvas();
    $font = Font_Metrics::get_font("arial", "normal","12px");

    // the same call as in my previous example
    $canvas->page_text(540, 773, "Page {PAGE_NUM} of {PAGE_COUNT}",
                   $font, 6, array(0,0,0));

    this above code for handling multiple pages header.

    it works to me, at end my code looks like:

    $html =
  '<html><body>'.
  '<p>Put your html here, or generate it with your favourite '.
  'templating system.</p>'.
  '</body></html>';
function pdf_create($html, $filename='', $stream=TRUE) 
{
    require_once('scripts/vendor/dompdf/dompdf/dompdf_config.inc.php');
    $savein = '';
    $dompdf = new DOMPDF();
    $dompdf->load_html($html);
    $dompdf->render();
    $canvas = $dompdf->get_canvas();
    $font = Font_Metrics::get_font("arial", "normal","12px");

    /*// the same call as in my previous example
    $canvas->page_text(540, 773, "Page {PAGE_NUM} of {PAGE_COUNT}",
                   $font, 6, array(0,0,0));*/

    $pdf = $dompdf->output();      // gets the PDF as a string

    file_put_contents("arquivo.pdf",$pdf);  // save the pdf file on server

    unset($html);
    unset($dompdf); 

}

pdf_create($html);

    I also got same error but when I use ob_end_clean() before $dompdf->stream() it worked for me.

    Below is my code.

    $dompdf = new DOMPDF();
$dompdf->load_html($html); 
$dompdf->render();    
$pdf = $dompdf->output();
$invnoabc = 'Bokkinglist.pdf';
ob_end_clean();
$dompdf->stream($invnoabc);
exit;

    I having issue with my pdf created by dompdf I open pdf file in notepad++ i found the below php error with dompdf

    Message:  "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"

    This happened due to old version of dompdf that could not be supported php 7 version after updating dompdf library the issue get resolved.

    download latest dompdf library here
