Posting Problems

I was very careful to check that the previous post was marked as scheduled for this morning at 5:00 A.M.  It was marked as scheduled.  All looked good.  I was out late tonight and when I got back it was not posted and was listed as "draft".  Something fishy.   Until I figure it out I am going to begin posting in the afternoon or evening for the next day.  If you have any ideas on what is happening here I would appreciate comments.
