Online users - Unknown location

Hi all;
I'm having this small issue here, as you can see in the attached images: users seems to be viewing unexisting links, most of them are probably related to my old phpBB forum…

Any idea why does this happen?

Thank you!

This an issue related to vBulletin. It maybe best for you to contact them

Thank you!

Are you using a custom 404? if so, make sure you add the skip sessioncreate definition.
Create a Custom vBulletin "404 Page Not Found" Page, and direct vBSEO to use it.

I am indeed. What should that do? I don't want to screw anything with urls and stuff…

That turns off the session on 404 pages, which will stop the online page error display, but will also show 404 pages as if they logged out.

Thank you Brian. This way, however, if someone tries to reach an unexisting page he will be redirect to a page as if he is not logged in. Anyway to just show the custom page that says that page does not exist without logging him out?

Right, it doesn't actually log anyone out. but it will show the login bar on the nav bar area instead of the users' name.

Odds are, 99% of your 404 hits WON'T be from members anyway.

Yes, you're right. Al take it as it is.

Thank you!
