[Plugin: Easy AdSense] Developers Ad Placement

This developer places his own ads in your site 5% of the time by default.

On the admin page near the bottom on the left find Support Easy AdSense by Donating Ad Space and change it to 0.

When you update the plugin or change your theme you should come back the the admin page and make sure it is still set to 0. Some people in the forums have been talking about it changing back to the default.
