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 C:\inetpub\vhosts\medihelp.com.mx\httpdocs\mhvirtstore\includes\functions\sessions.php on line 106
