Please upgrade to 2.3 here.
The 2.2 and earlier branches are no longer being updated.
Notifications not working (non-Inbox) in V184.108.40.206
I am running Version 220.127.116.11
Unlike the installation here, Notifications for my users are not working except for Conversations ('...sent you a message).
When a user comments on a Discussion the User starts, or @mentions
the User, these do not get added to the Notifications list on the User's profile page, and therefore do not appear as a count next to their Profile name in the menu.
Is there something I'm missing?
