OK finally working, mostly. In the GoogleAdSense.php file, you need to use the AdSense Unit IDs in the config, and NOT the Channel ID. This is what is confusing and the code needs to be re-written to reflect this.

coolgreany, Please can you eloborate on what you did to get it your working?
many thanks

Am on a Mac, using Firefox and Safari. Neither wants to show the ad.

I am also having the same problem. YouTube and the search bar work perfectly, but not the CHxx as the OP.

I am using MediaWiki 1.12
