hello
Im no techie or anything but what I do seems to work in at least getting the article to display.
the missed schedule thing tends to happen for me when I change the date to something prior to today’s date. WP freaks and calls it a Missed Schedule.
Seeing that, if I can get away with it, I then change the date to a time that is just ahead of the date and time I am in right now.
I cant get it to sit up like 2 years ago, but i can get it to present itself right now (which will be the past soon enough if you know what I mean.)
Thats not the solutioin but it is a minor work around given the circumstance that I cannot find whee in the hell wp-includes/cron.php is
All the best
Sam
