These 2 days we find the AdSense Advertises on our blog site do not display in Chrome browser, but they can display in Firefox and IE browsers.
We searched help from internet, seems there is no any valued information, some people just recommended to ask AdSense team or Chrome browser team. But there is no any clear answer about this.
We then think since ads can work in Firefox and IE, the problem should not caused by our code or any AdSense settings. maybe the reason is from Chrome browser.
Then we finally did a very simple operation and then our AdSense Advertises display again in Chrome:
Open Chrome settings and click Options
In Options windows, select Under the Bonnet, then click Clear browsing data… button
Check on Empty the cache, you do not check on other items if you do not want. then click the Clear browsing data button. This step will clear your Chrome browser cache.
After we cleared Chrome browser cache, we then can see AdSense Advertises display in Chrome browser again.
