I've got a site running an ad campaign and it's serving the ads using OpenX onto vBulletin. The ad campaign is on a few other sites and I can see one is using a very, very old version of phpAds and the ads are showing up ok. Now, when this site shows the ads they don't appear right and firebug tells me: Why would all those other sites be allowing Location.toString but not this site? What could be locked down (the admin is very security conscious) Any clues? thanks Sarah
