Google Adsense in my RHTML templates not showing up

This is quite weird. I’m trying to put a few Google ads in my app to
test placement, but they don’t show up. I’m in production mode and
have tried restarting the server etc.

If I view page source the code is right there and it all looks good.
I’ve put the Adsense code in some partials along with in my layouts/
application.rhtml file. If I take the exact same code and put it in a
static file under: public/test.html it shows up fine.

I know there are a million and a half Rails apps out there with Google
Ads, so I’m sure I’ve overlooked something small. Has anyone else had
this issue? thanks.
