Adsense approve my site last week and still no add shown their, only yellow image/screen on that particular area. does adsense take time to show, if yes, then how much??
I think after approval adsense start to show ads within few hours to 24 hours hardly. I think you should check once that your browser is using adblocker or any other related extension or not. You are entering google code manually or google showing ads automatically .... i think these can be reason also. If you can share your website URL then we can check what is happening more clearly.
Are you sure they approved it? Or did you just pass the first stage of the process? Can you post an English translation of what the "approval" email said?
