There may be a simple explanation and this may be much ado about nothing. I'm not an expert!
I was looking at some of my page code and saw my adsense "google_ad_client = "pub-#*$!#*$!...";
I was looking at that same ad in my adsense account and noticed that the code shows as "google_ad_client = "ca-pub-#*$!xx.....";
I get the "ca" but I don't get having two different versions. It seems minor but the way my account is tanking right now I'm a bit paranoid. I'm a bit of a scared chicken right now but I don't like seeing two different versions of a code.
Does this affect anything or is this much ado about nothing?
