I manage to find out to make the virtual include work on TPL.
1. you need to know if your hosting allows virtual include, some shared hosting does not allows it.
2. luckily I found a way around to make this in TPL, instead of putting in the header I put it on the footer, the footer loads to all the pages of the site. Its, because if I put the tracker in the head the site goes blank.
{php}
include('tp/ssi_in.php');
{/php}
then this goes to the body:
<img src="/tp/img.php" width="0" height="0" style='display:none;border:none'>
3. I check the stats in the admin panel, and its counting the stats just fine.
Incoming traffic tracker on the .htaccess just count the trades that goes the index and not for the pages, tnx to ipoli for reminding me that.
Now its working just fine with tpl. And Tradepulse ROCK!
