Whydowork adsense

I have whydowork adsense plug in on 40+ blogs and in the last 3 or 4 days the position of the adsense ads has moved to the very bottom of each post.

despite trying various changes to the position it is always at the bottom of the post.
I have yet to find any of my blogs that this has not happened to.
I run about 30 different themes.
They have all been running fine for several months with no problems.

They are set to appear at the top middle.

http://www.skyline1949.com is a typical example.

How can I fix this?
