Hello, I upgraded to 7.5.4 on tuesday and everything seemed to go fine. I started receiving complaints from the other developers accessing the machine that they could not log-in to mambo. I did some investigating and found that session support is broken in php. New sessions are created but the data does not persist. For example: You can log-in to mambo and see the control panel screen, but clicking on any button brings you back to the login screen. Each time you log-in a new session file is created and the session entry is added to the database. The cookies are also on my client machine. I added :Code: <?php print_r($_SESSION) ?> but the array is always empty. All of these logins worked prior to the 7.5.4 update. I don't think php was even included in the update but somehow the session support has changed. Any ideas?
