Hi I've just added a new site to the co-op and am attempting to run the code via php include files. The ads are showing on the pages but when I validate the account it tells me account is not validated and to check the URL/forum type. The site currently has 155 pages indexed in Giigle (site:www.url.com) I have all the files setup on a central domain - www.central-domain.com (not my real domain) in an include folder. In there I have a file called dpcoop.html. In this file I'm using the php code which calls the DP include: I've included this code on this domain (the one I'm having problems with) as : I have the ad_network_245.php and ad_network_ads.txt files installed on the central domain in the root folder - permissions are set correctly (666 for the txt file) The ads show perfectly on the target domain, but the account won't validate. Does anyone know if the ad_network_245.php and ad_network_ads.txt files need to be on the target domain for the account to validate - or does the validation script check for something else I may have missed? I'm trying to centralise everything to reduce maintenance when I need to upgrade the script - doing it this way I can just upgrade everything in one place and all domains are upgraded. Be nice if I could get it to work. Any and all help would be greatly appreciated. Thanks Mike PS. I have the script working well on several other sites so hopefully that reduces the liklihood of "user error" - but doesn't eliminate it
