Look, this has happened to me a few times now, and my blog is a week old. My blog seems to have reset itself to the last theme I used, and my two new posts no longer exist. I have put a lot of hard work into the posts I make, and now they are gone - however, I can still see them on my homepage (where the blogs I follow appear), and I'm still receiving likes, so I have to assume that they still exist. Also, on my dashboard, it says my blog is running the wrong theme, and that I only have one post.
The blog I need help with is runsparklerun.wordpress.com.
