AdSense – yellow box

Couple of reasons:

1. Your AdSense account or ad may not be approved yet

Solution: wait

2. You may have some CSS that's making the background yellow

Solution: change the CSS

If you're running WordPress some installs, apparently (it wasn't the case for me), have the attribute set to yellow by default.

A final note: there are some good WordPress plugins which make the job of adding AdSense into your blog easier.
