The script is:
	session_name("ID");
	session_save_path("sessions");
	session_start();
	session_write_close();
	if ( !isset($username) ) session_destroy();

first error for session_write_close():
Warning: Failed to write session data (files). Please verify that the current setting of session.save_path is correct (sessions) in c:\server\xmlbb\board.php on line 6

second error for session_destroy():
Warning: Trying to destroy uninitialized session in c:\server\xmlbb\board.php on line 7

With an earlier version of php the script was running fine. Now with php 4.2.1 i get these errors. The Apache Server version is 1.3.26
