I was working on a specific page of my website, http://hummelcreative.com/wp-admin/post.php?post=5252&action=edit, and I was trying to add additional content. When I went to hit the plus sign to add additional content, all of the content I had in there previously disappeared.
I tried going back to an older revision, and it wouldn't go. How do I get my work back? What did I do wrong that made this happen?
