I wanted to upgrade automatically but I already did some changes in the theme so I did a merge instead. One of the things I changed was to add the Ad code also to PAGEs ( I have 600+ pages where the majority of visitors go).

So, yes, simply

//Inserts the adcode

			if (get_option('swift_adsense_afterpost_enable') == "true"){

			if ($adcode=get_option('swift_adsense_afterpost'))

			echo stripslashes($adcode);}

exactly as in the single post pages
