No funciona la configuración de correo (gmail) OJS 3.1.2.1

Saludos :
Tengo un problema con la configuracion del correo he instalado la version 3.1.2.1 y todo esta bien pero ahora configurando el correo para que funcione no envia los correos. Sale #Email comopse.error# ya revise los logs tambien y dice

Aqui abajo la configuracion de mi pagina

Unless you have manually altered the screenshot, this indicates that you have a “1” value in smtp_password within config.inc.php. Instead, you will need your Gmail password here.

Could anyone solve this problem? I have exactly the same error, I’ve followed many strings on this issue but I can’t make the mail work. I clarify that the password is set in the config.inc file.
Thanks!
