online users module screwed up
 

Since I am still customizing none of my members know the new domain. But..yesterday there is i member(me) and 35guests? Saying the most users up to that date was 36(where did all the guests come from)? Today it says 1 member(me) and 17 guests, with the date of the highest amount of users and guests was 17 today. users online was 18? is there a bug here?

No it is not a bug, if the site is on the internet, spiders and bots will find it.

some of the other members, went to jira and supposed they classed it has a bug and will be fixed in 5.1.4. There were quite a few votes

Cool, I was not aware of that. :)

Yes its a known bug.
Vbulletin seems to close this out sometimes and its unclear if they are taking it seriously. This is a definite problem

This is your issue here which is set to be fixed in 5.1.7 - http://tracker.vbulletin.com/browse/VBV-13946

add
.wol-widget .widget-content > p + p { display: none; }

to your additional.css template and it will hide the most users online for now.

Then you can remove it in a year or two when vbulletin releases a fix ;)

Or just Edit Page and remove the module. :/
