I write a post. It appears on my site three times. But I am still sitting at the keyboard, waiting to see the "publishing blog" screen.
I click on my blog address. I get "This document contains no data" I also get this when I try to log in, when I try to leave comments, etc. Sometimes I can get past it. Other times, it's a lost cause.
I try to delete two of the three posts that are identical. For a day, nothing happens. Then, all three disappear.
