Adam,

 

I have followed your suggestions and if I put the mouse cursor on the time column, the time changes every 10 seconds, this is the same for all listed visitors, which is impossible that all the visitors keep clicking all together for more than 8 hours.

 

From what I can see now all the listed visitors are there since 6 hours, or less, the list keep growing and growing. Sometimes some users disappear from the list, but the big part is still there. It is random.

 

So the bug has not been solved.
