Adsense shows an 'X-Frame-Options' to 'SAMEORIGIN' error

Question

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

Answer 1

In my case the Google Publisher Toolbar was to blame - turning it off fixed the error.

Answer 2

I just started getting this error recently as well when using chrome.

From my searching around the interwebs, I found hte following information. It appears to be a bug in the webkit engine (chrome, safari, et al):

Invalid 'X-Frame-Options' header from google's Doubleclick response

Once Chrome (and maybe others) upgrade their version of webkit it will go away.
