[resolved] New install - print button causes 500 error

bsargent

This is a new install of 1.12.2 on fresh install of Windows 7 running IIS 7.5, PHP 5.6.31 and MySQL 5.7.27. If I try to print anything I get a white page with helpdesk.xxxxxxxxx.com is currently unable to handle this request.
HTTP ERROR 500.

I was really excited to find osTicket and I'm hoping someone can help me sort this out.

I turned on PHP error reporting and receive the following when trying to print the ticket that get's added as part of a fresh install of osTicket.

Fatal error: Uncaught exception 'Mpdf\MpdfException' with message 'Temporary files directory "C:\Windows\TEMP" is not writable' in C:\inetpub\wwwroot\helpdesk\include\mpdf\vendor\mpdf\mpdf\src\Cache.php:17 Stack trace: #0 C:\inetpub\wwwroot\helpdesk\include\mpdf\vendor\mpdf\mpdf\src\Mpdf.php(983): Mpdf\Cache->construct('C:\Windows\TEMP') #1 C:\inetpub\wwwroot\helpdesk\include\class.pdf.php(70): Mpdf\Mpdf->construct(Array) #2 C:\inetpub\wwwroot\helpdesk\include\class.ticket.php(3119): Ticket2PDF->__construct(Object(Ticket), 'Letter', NULL) #3 C:\inetpub\wwwroot\helpdesk\scp\tickets.php(498): Ticket->pdfExport('Letter', NULL) #4 {main} thrown in C:\inetpub\wwwroot\helpdesk\include\mpdf\vendor\mpdf\mpdf\src\Cache.php on line 17

I tried giving the IIS user full permissions to the TEMP folder but, it made no difference. I tried adding Everyone with write access and that made the print function work. What user account (rather than Everyone) should be given permission to the TEMP folder?

bsargent It could be restrictions in PHP/IIS too - have a look in your php.ini file for open_basedir, and if it's set, either add the TEMP folder to the list or change it to 'none'

If I remember correctly IIS runs as <localhostname>/IIS_IUSRS, so you would need to give permissions to that user, not the IIS user.

Hi bsargent

i have exactly the same problem. Apparently it's not the IIS_IUSRS that generate the PDF, did you ever figure out which user needs to have the permissions to write the pdfs?

Thanks!

Nevermind, i figured it out. Maybe useful for other IIS Users:

I had to give pemission to "<localhostname>\IUSR"
