I noticed that phptrak.php writes to index.html, not .php, so I changed that, and the link-throughs (or referrals, or whatever the term is) then worked, but were not logged.
It's a nifty little thing but I can't seem to get it.
1. I do have php support.
I can put the URLs in myself and such, but if someone can help me figure out what needs to be done to get it to work, I'd be really appreciative.
