I this has to have been asked before but I did search for it and I'm not finding it.
How do I get WordPress to use the Google Adsense for Search unit I setup?
I'm not sure if it is a hosting issue or normal WordPress behavior. I've seen enough though to suspect it is noromal WordPress behavior. I found AskApache Google 404 Plugin but don't understand how to get it to work. I put my key in it. It seems to be working on the pluggin settings page.
If you can point me to the correct place to read, I'd be happy wiht that so I can ask a more researched question.
