I'm running a one page site with index.shtml on a windows host (godaddy). I've uploaded ad_network_###.php and ad_network_ads_###.txt as well as placing the <!--#include virtual="/ad_network_###.php" --> into the web page code itself. Upon running, Error processing SSI file shows up on the page where the ads should appear. Is this a problem on the hosting side or is there anything else I need to do? Thanks!
