Udate (after changed PHP from v 5.2.6 to v 5.5.11): 1.  In the 'system.php' the 'config.php' couldn't call then change its name to 'config_5.5.php' then it work done. (something is confused)
2. in 'functions.php' and the headers of the pages are error because them can't echo $_SESSION['login'] if the user have not login, then fixed them by checking it before echo.
