I added a Content Box and a Banner to use for Google Adsense (I wasn't sure which to use). That didn't work because it placed the code in an iFrame which they don't like. So I deleted the Content Box and Banner. But the box is still visible on all pages (Bottom position). So currently there are no banners in the banners list in my admin panel, and the content box I made has been deleted and removed from the list.
I'm missing something here. How do I remove the box that is visible on my website?
