this will come in handy once they fix this hopefully you’ll be able to easily recover your previous theme without any issues once this.. blows over
also you shouldn’t try to fix your theme yourself right now, trying to edit it back probably won’t work and you might save over your old theme so if/when they do fix it, yours might not return to normal. its just a hunch tho, i’m not sure either way
what i would recommend to everyone right now is to go to google and search your blog. from there, IF you haven’t told tumblr not to let google track your blog, you can click on the arrow to the right of the url and access a cached copy of your blog. view the source of that page, copy everything, and save it as an html file somewhere on your machine. you cannot drop this code directly back into the theme editor, but it will let you keep your css.
bet somebody at yahoo is having a real bad day right now 👍
this also works with Bing, A+ methods
