It appears that for some people's sites, that the adsense server thinks it is being called from pages that do not actually exist, it seems to be attributing some of them to dynamic ad serving systems outside of the true "target sites", some of these "non existent" pages (partner.googleadservices.com is a 404 ), even belong to competitors ad serving systems and platforms,( atdmt.com is a Microsoft system )..php includes are obviously also,"dynamic"..and some widgets are confusing it..
But not everyone who runs adsense via "includes" are having the warnings*..
Blocking the pages that it is "imagining" and which are not on your site, might be a hack around it for now..
*But given the apparent randomness of what are being identified erroneously as "errors" by Google's adsense system..a "glitch" at their end seems the most likely explanation, a "glitch" that only they can fix..
