What's Up With My Template?

Okay, I seriously have no idea what's happened to my blog template. I didn't get into my template to switch anything. Is anyone having problems with their template? Is it just a homeschoolblogger thing? If not, has this ever happened to you before? Could someone else have gotten into my template? Kind of like identity theft isn't it...blog-template-theft. Well, who do I report this too? Hmmm?
