tienes q buscar en tu php.ini estas lineas...

; Argument passed to save_handler. In the case of files, this is the path
; where data files are stored. Note: Windows users have to change this
; variable in order to use PHP's session functions.

session.save_path = c:/php/tmp_sessions/


y claro, poner la carpeta correctamente,,, si no la tienes la haces y pones la direccion...

un saludo
