Please check the php.ini file to see what your tmp folder is actually called and where it is located.

Either mpdf is using the wrong tmp folder or php is...

Hi Kevin and thanks for your assistance.
I made the two fixes you reported and my Host manager told me that the permissions are correct. I'm attaching JPGs of permits, are they correct?
I have clean installation but it doesn't work, the PDF doesn't print, thanks.

@absolute

Then you should be receiving an error in your Apache/PHP error logs. We need these errors for further assistance.

Cheers.

Hi,
osticket uses the system temp folder for generating the pdf and not mpdf/tmp. So check what sys_get_temp_dir() returns for you and set the permissions for osticket on that folder, or use the 'sys_temp_dir' ini directive to set it to a folder that is writable.

If I comment the function as below it deletes the session links in / tmp, work! Can I leave it like this or write without deleting it in the / tmp?
Thank

/** @var \DirectoryIterator $item */
	//foreach ($iterator as $item) {

// if (!$item->isDot()
// && $item->isFile()
// && !$this->isDotFile($item)
// && $this->isOld($item)) {
//
// unlink($item->getPathname());
// }
// }

Maybe this will help you:
https://www.templatemonster.com/help/open_basedir-restriction-in-effect-filex-is-not-within-the-allowed-paths-y.html

Essentially your /tmp/mysql.sock file is not accessible as /tmp is not in open_basedir's allowed paths. All you need to do is add the /tmp directory to your open_basedir's allowed paths or move your socket to a directory that's already in your allowed paths.

Cheers.
