What potential issues could arise from incorrect session.save_path configuration in PHP?

Incorrect session.save_path configuration in PHP can lead to session data not being saved or retrieved correctly, causing issues with user authentication, shopping carts, and other functionalities that rely on sessions. To solve this issue, ensure that the session.save_path configuration points to a valid directory on the server where PHP has write permissions. 

// Set the session save path to a valid directory
session_save_path('/path/to/valid/directory');

// Start the session
session_start();
