Hola!
Estoy intentando abrir un foro SMF, ya subi todos los archivos, pero al momento de abrir el install.php me saca el siguiente error:

Please inform your host that the session.save_path specified in php.ini is not valid! It needs to be changed to a directory that exists, and is writable by the user PHP is running under.


Click here to try this step again.

A que se debe esto.... gracias.
