Hello, I use Mambo system, i have placed both the ad_network_289.php,ad_network_ads_289.txt in the main directory, set up file premission of 666 to both files, i installed an ad code plug inside the mambo system that let me just enter a code that will be placed on all pages, i placed this code- <?php ini_set ("include_path", ini_get ("include_path") . ':../:../../:../../../:../../../../'); include (' home/yosef/domains/455mb.com/public_html/ad_network_289.php'); echo $ad_network; ?> i then validated the account, and it is not validated and the ads are not showing in stage 5, about the above php code it says- Note: If your files are in sub-directories, you may need to use the full path to the ad_network_289.php file. If they are already PHP files, you will not need the opening/closing PHP tags. as you can see i placed the full path to the file, what are the opening/closing PHP Tags? what else can i do? Thank you, Joseph
