Hi, we use both HTTP and HTTPS. HTTPS is used on the part of the website that deals with our client's sensitive data. HTTP is used elsewhere. We use AdSense all over our web. The problem is that on HTTPS pages, some AdSense ads break the security protocol. Various browsers show different types of warnings of "mixed content" and "page not entirely secure" etc. to inform the visitors that not all content on the page is covered by secure HTTPS protocol. These warnings obviously scare our visitors. And yes, the problem is really AdSense and only some of the ads, not all of them. Most of the ads are OK, they are simple and do not contain additional resources, but some ads are more complex and do not respect HTTPS protocol and load resources from HTTP URLs. And yes, we do use the right AdSense code as suggested here https://support.google.com/adsense/answer/10528 : <script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script> Code (markup): Do you also experience this problem on your HTTPS sites? Is it possible to solve it without removing AdSense?
