Reply To: Notifications with scheduled topics

Future publishing depends on cron jobs. If you don’t have lots of visits, you’ll need to set up a real cron job as opposed to letting WP’s faux cron take control of it.

Depending on the number of users that are getting notifications, you should also set the background notification checkbox (in your screenshot) as your participants may start seeing browser timeouts when they post anything.

SiteGround has a nice post about replacing WP’s cron with real cron jobs:
