I tried signing up for the "On Site Advertiser" service but the page will not accept my logo. It is the right size, it is even displayed on the sample page after I upload it, but it will not stay on the Google server.
There is also nothing special being displayed on the AdSense ads on my site to inform people that they can sign up to advertise on my site. The "service" does not seem to be working. Is it working for anyone else?
