What I need to do to activate sending emails for new posts? As I mention I use Kunena as upgrade of FireBoard and until one week ago I received emails for new posts
If you upgraded from FB you may have lost all subscriptions (FB had a bad security bug and if fixing it fails, Kunena just drops all subscriptions). Look if you are really subscribed and then try to post into that thread..
I checked, I didn't lost subscriptions. In addition I unsubsribed from one topic and afret that I subscribed again. After this I tried agan - still no email for new messages.
