Errore arise in production (webserver is ISP owned). No problem during test on "localhost" on my machine: software works properly under ISS/WinXP. Therefore I guess I cannot try last CVS solution: if you think it is available, tell me, and I'll endorse your advice to my ISP. Do you think I should have appended this report to any of the previous ones instead of opening a new one? To which one, in your opinion? (If so, pardon me). Thanks. Reproduce code: --------------- <?php # Script 12.13 - logoutadm.php require_once ('../includes/config.inc'); // Include the configuration file for error management and such. require_once ('../authentication.php'); // connects to mysql + defines functions + ob_start() + session_start() include_once ('../includes/admin_header.inc'); // administrator page header ?> <H2 id=essentials><A href="/" rel=bookmark>Logout</A></H2> <?php if (!isset($_SESSION['usera'])) { ob_end_clean(); // Delete the buffer. header ("Location: http://" . $_SERVER['HTTP_HOST'] . "xxxxx.php"); exit(); // Quit the script. } else { // Logout the user. echo "<h3>Session = " . session_id() . "</h3>"; // for test purpose $_SESSION = array(); // Destroy the variables. session_destroy(); // Destroy the session itself. setcookie (session_name(), '', time()-300, '/', '', 0); // Destroy the cookie. } echo "<h3>Logout successful! </h3>"; // Print a customized message. ?> <?php // Include the HTML footer. include ('../includes/admin_footer.inc'); ?> Expected result: ---------------- As in test: user logged out, with no error displayed. Actual result: -------------- "session object destruction failed" error returned and displayed by error handler routine. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=29419&edit=1
