I have added your changes, and uploaded. I had a couple errors, but fixed those (my own fault - I added another usergroup).
But, while I no longer receive errors, nothing seems to have changed on the 'who's online'. It still shows everyone like normal.
I created a test user since guests can't view the who's online at my forum. The test user was just a regular member. I had a moderator log onto the board, and I logged in as the test user. But I could still see where the mod was and what they were doing.
