I've gone to GoogleAds, created the ads and gotten the codes, and pasted them into Yola. I've tried to paste them into both the GoogleAds widget and into the HTML widget. No matter how I try it (or how long I wait), they don't show up. The site shows a big empty space where the ads should appear. When I'm looking at the page from the editing view (logged in to Yola), it shows an empty HTML or Adsense widget box. Any thoughts?
