My site is mylifeunpinned.com . I'm using the Genesis framework with a child theme. But my problem occured when I clicked on the "Live Preview" of the wordpress Twenty Twelve theme that I had downloaded a while ago. When I cancelled the "Live Preview" my theme home page was suddenly missing. In it's place was a new page titled "Home" that was mysteriously created in my "Pages" section as a result of the "Live Preview". I deleted the new "Home" page, but now it says that the page I'm looking for no longer exists and gives me an archive page instead. I also tried deactivating all of my plugins, no help. I've done a system restore through my hosting site, no help. I found one other forum thread about this same problem but it was not resolved. No other parts of my blog were affected by this bug, only the home page.
