Hi, I installed some days ago the script for "Coop Advertising Network" (still pending ) and I get some warnings in my log from $_SERVER['PATH_INFO'] and $_SERVER['HTTPS'] : 8: Undefined index: PATH_INFO File: /var/www/wt/ad_network_292.php Line: 78 8: Undefined index: HTTPS File: /var/www/wt/ad_network_292.php Line: 97 is possible in the future (on the next script version) to check this variables if are seted up ? (something like is_set($_SERVER['HTTPS']) ) Regards
