In that time I was not online and 15 comments were made.
Late Wednesday our time it reverted to drafts in my posts, as original draft with just three photos, no text.
Thankfully I have had my blog post emails sent to myself and saved as backup for ages now, so simply re-pasting it, and re-publish! Curious indeed.
Even curiouser when I just re-published it, it put Tues date up with all comments, and slightly new title. I am so puzzled by all this!
