note 58118 added to ref.session

Can someone help me- I have a PHP website where my users are logging into it, and after several minutes, the session times out, and sometimes even changes users from one user to another- each page begins with- Something similar to this- include_once("globals.php"); //include("globals_messages.php"); echo("<table> <tr><td align=center><b>Welcome Message</b></td></tr> <tr><td class='TD_DARK'>" . $g_welcome_message . "</td></tr> </table><br><br><br>"); if($g_welcome_showAnnouncements == 1){ $code = $_SESSION['code']; $sessionuserlevel = $_SESSION['userlevel']; Sessions are all handled via that- What can i do to help reinforce the session? THank you for your help!
