Session_write_close() Warning On Site

[big cod]

Any body seen this at the bottom of there site pages http and https ?

 

"Warning: session_write_close() [function.session-write-close]: Your script possibly relies on a session side-effect which existed until PHP 4.2.3. Please be advised that the session extension does not consider global variables as a source of data, unless register_globals is enabled. You can disable this functionality and this warning by setting session.bug_compat_42 or session.bug_compat_warn to off, respectively. in e:\sslroot\gforce-rc\catalog\includes\functions\sessions.php on line 197"

 

Any ideas on how to remove it , My hosting company doesn't give me access to the php.ini file so I cant remove the warning text.

 

Cheers
