bill_h on "[Plugin: BackUpWordPress] backup wordpress no schedule option"

Hi. I have been trying to setup a schedule for backing up, with BackupWordPress, but the only option it gives in the settings screen when clicking the down arrow is manual only. How do I get it to change so that I can set up a schedule?
