Ads do not show

I'm relatively sure this is user error but for the life of me I can not get the ads to show. There's a blank space where they would be but no ads. I've tried it in multiple browsers and it's the same thing.

I'm running a single site (currently) with the BuddyPress Fun child theme, BuddyPress, and Google Adsense. Admittedly, I have problems sorting Adsense out but it's what we chose to use.

Thoughts, suggestions, and advice on ads would be appreciated.
