I'm getting this warning when running a PHP 5 script that i wrote. What could be the issue?

Warning: Unknown: 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 Unknown on line 0

Your script is probaly relying on register_globals being on, BUT without knowing what the script is ....




.... it really is impossible to tell.
