Adsense (text widget) Not showing in single posts.

I’m currently using the default text widgit to add the adsense code to the sidebar on my site. Unfortunately the ads are only showing on my frontpage, not on any of my single post pages. I can see the adsense code when I view the source of the single posts, just not the ads themselves. Does anyone know how I can fix this?

Here’s my site: Keepingittasty.com

Oh and I’m currently using the suffusion theme if that is any help.

Thanks!!
