Something strange is it Yesterday I had 1 Known user logged in to our site and I could see him on stat as Known Users whith his nick name. Today when I check I can still see his visit in Right Now but not as Known Users, his track is now classed as Other Humans. I had in settings activated Outgoing click which I now have turned off, can that part generate tracked known users to be other humans??
Edit: The above mentioned senario I can now understand why this happen its due to when known users logout and they will switch from known to other human as session is set to 1800 for 1 IP:s visit to remain. When I filter on his nick name I get his as Known Users.
Also worth to mention when I had the above cache uncomment in config file I got one users track as above but an other known users IP which was logged in wasn't tracked at all so the latest version might be instable?
Edit: This users track when I filter on his IP or Nick name his track is not logged at all.
I hope above information will help you to drill down to root cause as I love your stat and really want it to work :-)
