Ryan, your tip helped me to figure out what happened;
I actually I have an Adsense ad "as you can see" in the feature area.
I added the ad usind the theme insertinon php function of "Adsense Integrator",
but I didn't noticed that the plugin got disable probably while I was trying to update
it automatically.
Just reactivating "Adsense Integrator" solved the issue
Thanks a Million Ryan
