Hi -- The plugin does not seem to hook in to the wp-cron. As a result, the job is not being run automatically. I checked the scheduled wp-cron jobs and don't see any for this plugin.
The following messages are seen on the plugin setting page.
Crontab warning: ydbfsPlugin->daily_update is currently not scheduled.
Crontab warning: ydbfsPlugin->hourly_update is currently not scheduled.
Any idea what needs to be done to set this up with wp-cron?
