Recently I noticed that all my websites give an error in Chrome console (removing adsense the error goes away):
Refused to display
https://googleads.g.doubleclick.net/pagead/drt/si?p=******&dpt=1
in a frame because it set 'X-Frame-Options' to 'SAMEORIGIN'.
Nothing was changed, I don't use iframe, Ads is still visible. But I don't like this error, I read about youtube and maps error, but didn't find any about adsense.
What can I do to fix it? Page of example: http://www.incinqueterre.com/en/trails-all
