It appears you don't have a cron setup.

When you installed una, did you copy the cron /path/ given at the end of the una installation? That is the easiest way to know what the cron job is, with its entire /path/; because the install detects it and gives it to you. But if you don't have it, i guess you can ask your hosting provider for it, or you can install a test UNA site and grab it from there.
