Hey there,

I am really sorry for the delay of this reply as it is a weekend for us here.

That total of number count is for your backend and frontend online user.

And i realised your site backend global configuration have set your user session to 5000 (http://take.ms/C79uu), mean if this user login user never logout on the site, this user session data will always appear on this table #__sessions.

If this user login their user account on different browser, it will got another session data for this user in this table #__sessions.

This is why that online user count result will appear more than the existing user count.

Hi Arlex,

I have now set this 1800 (30 hours), once this time is up, does it end EVERY session? Including people who have selected 'keep me logged in'?

Thanks
Katie

Yes, it will automatically remove those session record from the database for those user session already expired.

But if the user suddenly access your site maybe after 24 hour, that session will re-count again, mean it will count it from first minute, so this user session will be expired at after 1799 minute.
