I installed this mod a few days ago in my store which is not yet linked to the general public from my main site but which I've been testing at its URL on the web.
Anyway, it looks like supertracker was working fine for me (I can see the data in my admin area), but I sent the store URL to someone for a different reason and they let me know they see this error:
Fatal error: error traversing database - perhaps it is corrupt? in .../public_html/store/catalog/includes/geoip.inc on line 416
Which leads me to believe it's related to the geoip program which I loaded for this mod. Is there something that I probably need to do to correct this important fatal error (which again, I realize, is not fully related to this mod)
