If you are experiencing then problem “scheduled missed” when scheduling a post in WordPress, I found the solution on http://blog.5ubliminal.com/. Simply do the following:
- Copy the code shown below and save it as scheduled-mias.php.
- Upload the file to wp-content/plugins on your WordPress site
- From your dashboard, enable the plugin named Scheduled Mias
That’s all there is to it.
