I recently had someone ask me how to get spaces to show up within wordpress. This has been a difficult item for me to figure out. I have tried to hit return multiple times, I have added tables, I have tried using <br>, and have not been completely successful.
After searching online I found a forum that suggested the following (http://wordpress.org/support/topic/how-to-add-blank-lines-in-a-postpage):
<code><br /></code> <code><br /></code>
I believe that this may will solve the problem of getting spaces put back into wordpress. I am going to add two spaces below, save and then add another sentence.
It looks like it is working after saving and re-editing the post.
