"Ad Slot ID field is required." when submitting a block. Don't know what to do. Have never encountered this before with adsense.
you use this feature, the adsense code on your site only has 4 fields, a height and width, so that the inital iframe dimensions do not mess up the site's appearance, your publisher ID, and a slot ID.
Everything else is managed from your adsense account. This includes color, channel and everything else.
You should find a tab in your account that is called Managed ads.
The versions of the adsense module 5.x-3.x and 6.x-1.x support this new code.
You need to create ad slots in your google account and then paste the slot id into the block.
I bet Google will yank the old way of doing ads at some point, once enough pubishers get on the managed ads bandwagon. Just like they ditched referrals.
