I'm not sure how xF handles this number of users online. My last site had the 60 second interval but had counts of 1,500 or so. xF is much lower, does it not display guests? Thanks
In vB you were able to adjust the "session timeout" - the time in seconds that a user must remain inactive before their login session expires. This setting also controls how long a user will remain on Who's Online after their last activity.
In xF by default is 60min and unable to change without have to manually edit a php file....I think.
