What does this warning message mean when I turn on debug mode?

[lateral]

Hi guys

 

I turned on debug mode and started the Front Office and saw the following warning message:

 

Warning: tempnam() [function.tempnam]: open_basedir restriction in effect. File(/tmp) is not within the allowed path(s): (/home/5-web/54/11/rodpenroseracing.com.au/:/usr/local/lib/php/__applications/:/home/chroot_bind/php/php5/usr/local/lib/php/) in /home/5-web/54/11/rodpenroseracing.com.au/public/www/classes/PrestaShopAutoload.php on line 151

 

What does it mean and do I need to do anything???

 

Thanks

 

Regards

Greg
