Hello, I see the following Adsense alert for a long time (couple of months or so):
The following ad units have made ad requests with incorrect site information. This occurs when the URL of the server from which the ad unit has been served differs from the URL of the actual page where the ad will be displayed. Learn how to fix these errors.
I went to the page with recommendations on how to fix this but it does not apply for my site because i dont use I iframes or ad servers. And I have no idea what else that can be? Any ideas?
