Kingpin, been having a look at the site and stats. Could not find anything wrong with up, my stats are getting updated fine and shares is displaying correctly.

I am using firefox as browser though please try doing a ctrl F5 while on the page and see if it updates your stats.

The three different stats you see or posted :

Stats gets updated every 5 Minutes and the left side bar is the same php page displayed on every link you click.

Could be that your page is cached (ctrl F5) would help with this.
