[fernandodonster]

what is the problem with the code -displayed a warning that
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 asource
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.

The problem is exactly:

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 asource
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.

Without actually seeing the code that is all I can say...
