For those interested, after some email communication with Mihael, we managed to find where the bug is.
For some reason, when he copied and pasted the google adsense code, his editor converted the following:
into a link!
So in case you find that the googleAds plugin not working, edit your article in your editor and double-check that the script src is not converted into a link (you will see them in blue underlined text).
They should be in plain text.
