I'm having the same problem on a blog I put up in the last month or so, its tracked a total of 0 visits, but its taken comments, its been indexed, and I've had it stumbled by a few people which would have generated a few hits, but the WP-stats is recording it as 0 across the board.
The blog is at http://www.bobgregoire.com
Is it a compatibilitiy issue with other plugins perhaps?
Presently I have in the mix:
Add Post Footer
Add to Any: Share/Bookmark/Email Button
Akismet
All in One SEO Pack
FD Feedburner Plugin
Google Analytics
Google Analytics for WordPress
Google XML Sitemaps
Permalink Redirect
Podcasting
WP to Twitter
XHTML Video Embed
and just to be cute - Hello Dolly
I have not tried deactivating all of them yet, and testing one at a time, but I have deleted the Plug In and reinstalled it, and still no counting.
It "could" be that there is just no traffic coming in, but given my own visits from a totally different IP address, surly it would register something.
Anyone have any thoughts on this? I'm about to start a campaign with it and I need some metric to measure it with.
