hello, everything is ok for administrator when you check they can see others stats.
But for redactor without this setting (and he normaly should see his own stats) we see only the world "array" in place of his name and stats
as you can see you have global stats but not the one for the redactor.
that happend only when it's for our own stats .
i think the problem is because here should be a line with the name of the redactor instead of the list of posts.
