luceos if your email is successfully being sent from the admin email page when clicking test email then it's not an issue with flarum,
The test email is sent without any problems. There are only no notifications that have been activated in the UseraCcount.
luceos But if you're hosted with FreeFlarum you will need to get their help, we don't know how it's configured or see any errors.
We have been there. In the meantime it is hosted itself.
Which (free) service can you recommend? We would like to have notifications by email again.
