HTML_ToPDF, I'm stuck some help please

[Sjaakie]

Hi there,
I'm trying to get HTML_ToPDF (3.3) running on en dedicated server,
safe_mode enabled. Been trying for more than 2 days now, without success.
Have similar script running on my own personal server. Safe mode disabled.

This is what I did so far:
---
I copied html2ps, ps2pdf and curl into
/opt/guide/www.domain.invalid/HTML/config/html2pdf/, directory also
holds all HTML_ToPDF-files. Did chmod 777 to the specified folder.
Temp-folder is /opt/guide/www.domain.invalid/HTML/tmp (also 777).
The script:
---
// PDF (include class)
@require_once($_SERVER['DOCUMENT_ROOT']."/config/html2pdf/HTML_ToPDF.php");
$defaultDomain = "http://www.domain.invalid";

// PDF (path to html)
$htmlFile = $_SERVER['DOCUMENT_ROOT']."/pdf/input.html";

// PDF (path to pdf)
$pdfFile = $_SERVER['DOCUMENT_ROOT']."/pdf/output.pdf";

// PDF (settings)
$pdf = new HTML_ToPDF($htmlFile, $defaultDomain, $pdfFile);
$pdf->setDebug('true');
$pdf->setPs2Pdf('/opt/guide/www.domain.invalid/HTML/config/html2pdf/ps2pdf');
$pdf->setHtml2Ps('/opt/guide/www.domain.invalid/HTML/config/html2pdf/html2ps');
$pdf->setGetUrl('/opt/guide/www.domain.invalid/HTML/config/html2pdf/curl
-i');
$pdf->setTmpDir('/opt/guide/www.domain.invalid/HTML/tmp');
$pdf->addHtml2psSettings('break-table: 0');
$result = $pdf->convert();
Running the script returns:
---

/opt/guide/www.domain.invalid/HTML/config/html2pdf/html2ps -f

Error: there was a problem running the html2ps command. Error code

DEBUG: html2ps output is empty, so I tried to execute the command from
shell. Created a file test.php containing:
<?
exec('/opt/guide/www.domain.invalid/HTML/config/html2pdf/html2ps -f
/opt/guide/www.domain.invalid/HTML/tmp/CONF-4omnhC -o
/opt/guide/www.domain.invalid/HTML/tmp/PS-YJn3Ar
/opt/guide/www.domain.invalid/HTML/tmp/HTML-SDrxWw.html 2>&1');
?>

running '/>php test.php' returned;
---
Error opening resource file:
/opt/guide/www.domain.invalid/HTML/tmp/CONF-N4OHnA
*** Error opening /opt/guide/www.domain.invalid/HTML/tmp/PS-JXAcZk for
output

The generated files in tmp-dir are owned by 'nobody:other', only nobody
has rw-access, group other has r-access.

Why can't php open the file?
What actions to take to solve this?

Thanks in advance!
