I've just set up the code for the co-op for www.webmasterslovegoogle.com in this way. All my pages are shtml - so I've added the php include code in to a file called coop.php. I reference this in the shtml page as a <!--#include virtual="/includes/coop.php" --> Code (markup): The Coop - ad_network_236.php and txt file are both in the site root, the txt file has been chmodded. I'm getting duplicate blocks on the pages (very bottom) - am I doing something wrong. I tried adding a line to the htaccess page and it caused the browser to try and save the page rather than load it - when I added .shtml to the line. Including the PHP on the page using this method works for me on Text-Link-ads code. Any advice appreciated... Ok - I think I've fixed it - I dropped the initial include and added the ad_network_236.php code to the virtual include instead - it's working fine now.
