The Issue:

When the time allotted for a scheduled post to be published occurs, the post is not published, and a message within the Admin panel only says “Missed Schedule.”

After perusing around the WP forums for a bit, I came to realize that this is a hot topic for many 2.9 early adopters. After looking deeper into the forums, I found that this has been a potential issue with Wordpress versions since the release of 2.7. Some say the “Missed Schedule” mishap can be caused by a temporary “hiccup” with a site’s DNS. As I manage the DNS for the particular site I host, I knew this to not be the case. Further research did indeed provide me with a solution.

The Solution:

Apparently with all the new fancy upgrades to the WP core, a significant amount of time (in the web world this means milliseconds!) has been added to the time it takes to run the job that actually publishes a post. From what I can tell this is due to the number of hooks that data has to be run through to make it from the edit page as a draft, to the front page of your blog as a live post. The addition of running it through the scheduling cron job pushes it too far. Can’t we just extend the allowable time to publish a post you say? Here you go:

The time limit is set around line 230 in the /wp-includes/cron.php file. The default line will appear as such:

230

wp_remote_post( $cron_url, array('timeout' => 0.01, 'blocking' => false, 'sslverify' => apply_filters('https_local_ssl_verify', true)) );

As you can see, the limit is set to 0.01 seconds by default. I tried increasing the value in increments, and finally decided on 20 seconds. You may find that this can very from server to server, so play around with it for a bit to optimize it for your setup. So here’s the updates line:

230

wp_remote_post( $cron_url, array('timeout' => 20.0, 'blocking' => false, 'sslverify' => apply_filters('https_local_ssl_verify', true)) );

So there you go! If you’ve found yourself upgrading to a new version of WP and you are unable to successfully publish a scheduled post, try this out!

Hope they get this fixed soon!
