What could be causing the session problem described in the thread?
The session problem described in the thread could be caused by a misconfiguration in the PHP settings related to session handling. This could include issues with the session.save_path, session.cookie_domain, or session.cookie_secure settings. To solve this issue, you can try adjusting these settings in your php.ini file or in your PHP script.
// Adjust session settings in PHP script
ini_set('session.save_path', '/path/to/session/directory');
ini_set('session.cookie_domain', 'example.com');
ini_set('session.cookie_secure', 1);
// Start the session
session_start();
