Adsense cpc and ctr down

Hi friends,
I am facing some problem in Adsense earnings. I am getting same traffic but since 16,17 May, I am getting low cpc and ctr. My earnings down something about 40%. I am using flying press Load Scripts on User Interaction. I am not sure that I am facing problem from this option because I am using this option last 3,4 months.

Please disable it and test again.
