A Mystery........

I don't know what happened.  On the 17 of April I uploaded a photo of a magnolia bud that had survived the awful winds and rain storm.   When I uploaded the photo, the photo was rotated  a 1/4  turn.   It wasn't what I wanted, retried to upload it again with the same results.    I put in a title, a blurb, published it and was glad to see the  published photo and blurb.
      Yesterday, when I went to publish yesterdays  post,   I found that the post for the 17th  was gone.   I don't know what happened.  Maybe one of you, that is more computer savvy than, can offer some help
    After I realized what had happened, I went out and took a picture of the same subject and published it for that day.
It is a mystery to me.
