If you are using a custom style, that might explain it as this is set up for the default style.

yes m8 im usin costum style anyways thanks good work like always from u :)

I've just found it has a bug in Fire Fox Version 9.0.1
Will be looking for a fix as soon as, maybe this is why it isn't showing for some of you guys.

Spewing this has become a paid mod.
I was hoping the "free" version might have been updated a bit to have flags packed with it and what not.
It seemed to be the direction it was going in the early posts but then bang PAID.

Contemplates uninstall........

They are 2 totally different versions and there is no way to add locally hosted flags to an outside link easily. There was a lot of work and time put into the Advanced version, along with the ongoing support.

The Advanced version from Boofo has just been updated on the first page;

It will show the Country Flags in 6 places:

1) Member List
2) Member Profile
3) Postbit
4) Private Messages
5) Show Groups
6) Who's Online

I have the Advanced version, just waiting for the updates for the new 3 places it shows.
It's a great vserion, you can see who is online and postbit as attached, it also great with the mouse hover over the flag.

Installed so far so good.

Could not get it to work on my 4.1.4, gave up after three tries and unistalled.

So you imported the xml and then when you checked the Who Is On Line no flags showed?
Do you have a link to your site so I can see the site, it might gives me a heads up to what the problem is.
Also which browser did you use to check with?
IE really has many problems with vB and products.
Did you check using another browser, say FF or Chromium?
