Upgrade from 2.2.0 to 2.2.1 makes comments disappear
Just did an upgrade from 2.2.0 to 2.2.1. Extracted all files from ZIP, installed product XML, confirmation told me upgrade was a success.
All issues are now without any comment. New comments will appear as AJAX is activated, but they are not shown anymore after a refresh of the page. Issues are shown with 0 Replies.
The comments are still in DB, but they are not visible on frontend.
Rebuild issues, projects, etc. didn't help.
If you want, I can provide you with test data.
