I upgraded our JIRA from version 6 to version 6.1. Suddenly the Activity Streams are always empty. It is very annoying for the users who were very dependent on them. So I need to get the activity streams back.
What I have tried so far: 1. Reindexing 2. Creating a new widget for activity stream
What log can I look into to see what is broken? Do I need to create a new filter or something?
