What are common causes of the "open(/home/georg/sess_07413e5c5b1ba49a92b4340fc41d5100, O_RDWR) failed: Keine Berechtigung (13)" error when trying to start a session in PHP?

The "open(/home/georg/sess_07413e5c5b1ba49a92b4340fc41d5100, O_RDWR) failed: Keine Berechtigung (13)" error typically occurs when PHP does not have the necessary permissions to write session data to the specified directory. To solve this issue, you need to ensure that the directory where PHP sessions are stored has the correct permissions set to allow PHP to write session data. 

// Set the session save path to a directory with appropriate permissions
session_save_path('/path/to/writable/directory');

// Start the session
session_start();
