What are the potential reasons for the session timeout issue in phpMyAdmin despite adjusting the config file?

The session timeout issue in phpMyAdmin may persist despite adjusting the config file due to conflicting settings or caching mechanisms. To solve this problem, you can manually set the session timeout value in the PHP code using the session.gc_maxlifetime directive.

// Set session timeout to 1 hour
ini_set('session.gc_maxlifetime', 3600);
session_start();
