Had been working great (or appeared to). Stats are 2nd to none. I had just migrated my site to a new environment (from xampp windows to linux turnkey wordpress vmware) and was debugging issues. I was seeing regular apache error log segment faults every few minutes and Linkedin.com could not reference my site (i.e., linkedin would think on my url for a few spins and then not show it). Removed statpress and both problems went away.
Humorously, had donated to the plugin within the last two weeks.
I will certainly try future versions to see if it works on my site again.
