Error generating PDF files ( delivery slips)

[gonaker]

I have huge problem with generating pdf files. When try to generate delivery slip it only show a blank white screen.

 

I use Prestashop 1.6.0.9

 

I have found this error message;

 

Warning: tempnam(): open_basedir restriction in effect. File(/customers/7/e/a/fylldinac.nu/httpd.wwwcache) is not within the allowed path(s): (/customers/7/e/a/fylldinac.nu/httpd.www:/customers/7/e/a/fylldinac.nu/httpd.private:/customers/7/e/a/fylldinac.nu/tmp:/customers/fylldinac.nu/fylldinac.nu:/var/www/diagnostics:/usr/share/php) in /customers/7/e/a/fylldinac.nu/httpd.www/classes/PrestaShopAutoload.php on line 151

 

anyone who could understand this?
