Losing My Background Image

That’s me in the corner…
Uh, somehow Radio streamed my home template in a way that changed the syntax of the body style declaration. It added an <a href etc. around the url, the way you would turn a raw address into a link, but not in my template!
Any idea why this is happening and how to prevent? I’m hoping that replacing the file will force it back, though I still don’t understand how to control upstreaming of templates.
