Hello,
I've just started a new blog with Atahualpa 3.6.1 and my problem is that there are Chitika ads on each post... I've never put it in so I tried to remove these ads but didn't find where to do this (adsenses ads are mine though).

Just have a look :

Thanks for your help !

first step is to disabling all your plugins to see if one is doing it.

My mistake... The culprit was Easy AdSense...
