What could be causing the issue of being logged out after logging in on a PHP clan page?

The issue of being logged out after logging in on a PHP clan page could be caused by session management problems. To solve this issue, you can try increasing the session timeout value in your PHP configuration or code to ensure that users stay logged in for a longer period of time.

// Increase session timeout value
ini_set('session.gc_maxlifetime', 3600); // 1 hour

// Start session
session_start();
