I’m having the same problem. In another thread with Erica, the problem was declared resolved. It’s not resolved for me. I’m a fairly new user. I just posted a blog entry which looked fine when I composed it, but in its posted form, there are no line spaces. Despite the fact that I added some within the blog editor. Sometimes I compose in Word. Sometimes in Evernote. But I always do the final editing right in the blog editor. Very frustrating.

Look at the May 30 entry. There should be spaces between all paragraphs except the numbered list, which I left single-spaced.
