Site is a regular php setup, was working fine until I updated ad_network.php file. Cleared out ad_network_ads.txt file, made sure it's writable but ads just display as 'array' and site fails validation. Any ideas? OBTW - ads.txt file is getting the ads OK
Yep, needed to update the footer code too - that'd be worth mentioning a little more prominently I think. Email says that only the php file has changed
