Not a SINGLE Adsense plug-in worked for me. I used the Arras theme and tried out about 10 different top Adsense plugins with all these special features I didn't need.
This plug-in when brought up has the most basic interface and is the most straightforward plug-in I have EVER seen for WordPress. I wish more developers would strip things down like this or at least provide a basic version.
None of the other Adsense Plugins worked AT ALL for me, but this worked immediately without any tweaking or messing around.
I give this 5 stars and HIGHLY recommend it!
