I've just tried a new theme for my blog excusesandhalftruths.com, The Columnist. When applied, it seems to have caused all my content to vanish. All I have is half of the site title: it looks as if everything has HEAVILY right-justified. Currently checked the site on both Chrome and Firefox on both Mac laptops, with the same results. Applying Twenty Twelve gives the same result. Reverting to my old theme (Twenty Ten) seems to fortunately solve the issue (otherwise I'd be tearing my hair out at this point) but I'd be interested to know if there's anything I can do, as I'd dearly love to try out some of the new themes available.
The blog I need help with is excusesandhalftruths.com.
