I just set up the co-op on http://www.shop-for-flowers.com and am getting the error. I went through all the setup steps twice. Sill an error. See below. What now? Warning: main(ad_network_172.php): failed to open stream: No such file or directory in /home/shopfor/public_html/index.html on line 61 Warning: main(ad_network_172.php): failed to open stream: No such file or directory in /home/shopfor/public_html/index.html on line 61 Warning: main(): Failed opening 'ad_network_172.php' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php:../:../../:../../../:../../../../') in /home/shopfor/public_html/index.html on line 61 I found the error. I was using an old code from previous site. Thanks Bill
