can anyone explain what is the undefined variable?
Than you very much.

Hi @mujiec,

I think the warning is cosmetic (and will disappear once you upgrade to OJS 3.1.1, which we’ll be releasing shortly). The SMTP messages relate to your SMTP configuration in config.inc.php – double-check that your credentials are correct.
