open_basedir restriction in effect

[jeremyotten]

I cannot upload files from an URL in my servicedesk..

The programmer debugged it to this

I uploaded a simple test php script here http://support.randomsolutions.nl/scripts/test.php

the output is:
Warning: is_writable(): open_basedir restriction in effect. File(/tmp) is not within the allowed path(s): (/var/sentora/hostdata/zadmin/public_html/support_randomsolutions_nl:/var/sentora/temp/) in /var/sentora/hostdata/zadmin/public_html/support_randomsolutions_nl/scripts/test.php on line 22 bool(false)


How can i fix this @ the serverside?
