I set up campaigns, zones and banners a year ago and they've been running on my sites just fine but all of a sudden on the same day all ads stopped displaying on my sites. It's not a script or server side problem because if I set up a new ad zone, attach banners to it and display that zone's ID on my sites the banner will display. Is there a setting I've missed on the other zones? They're set to unlimited impressions and there's no end date. Any ideas? Thanks.
