I am having this same problem kinda.

I used the weblog script.

Somehow it is loading the page twice, I put on my index page a simple script to log refering url, browser, ip etc.

Then in mysql when I check I get 2 entrys per visitor, one will show the url they came from, the second is from my site.

So I know something with global.php is causing it to load twice.

It is not in a while loop either.
