I have cleaned my site of that code and since then I have upgraded my joomla form 1.07 to 1.015.
Everything seams to work fine but i have noticed that... In my site before being hacked, i had a good traffic count. usually 100 to 200 guest from all over the world at any time during the day, but now Joomla only registers a few guest.

I have checked my servers stats to see what happened and i have discovered that i am still getting the same amount of traffic as before ( about 2500 visits a day).

here is My question is..... why is Joomla Who's online module only showing a few guest when there are manny more guest browsing my site?

as a matter of facts i have published my statistic module from joomla.
In this module i can see that everytime i refresh my browser the Visit conter will add many more visits, witch tells me that manny guests are visiting to my site.

soo Then... why who's online module only shows a few?
