I am currently in version 3.1 of WordPress and I have a problem with planning my post. In fact, whenever I plan a post, it is written: "Scheduled missed. Could you help me please.

Thank you in advance

Due to your server configuration, you may need to use the alternate cron method, which uses redirect rather than http loopback.

Try adding the following to your wp-config.php file:

// Alternate cron method 
define( 'ALTERNATE_WP_CRON', true );

Thank you for the answer. The bug is fixed. – Onita Apr 27 '11 at 8:58
Well, this does work for me. But I don't think I could use it in a production environment. Before you all go rushing to add this line of code check this out wordpress-hackers.1065353.n5.nabble.com/… – crmpicco Nov 1 '13 at 14:55

The missed schedule is due to wordpress timeout in the cron process. Go to wp-include/cron.php, around line no 248, change the value of 0.01 to a larger number.

in my case, I changed from : wp_remote_post( $cron_url, array( 'timeout' => 0.01, 'blocking' => false, 'sslverify' => apply_filters( 'https_local_ssl_verify', true ) ) );


wp_remote_post( $cron_url, array( 'timeout' => 7, 'blocking' => false, 'sslverify' => apply_filters( 'https_local_ssl_verify', true ) ) );

remember this cron.php is a wordpress core file, it will get overwritten when you update your wordpress core. So after every update, remember to change the value again.

If this doesn't work for you, make sure your timezone setting is set correctly. The setting can be found at: Settings > General

No - do NOT change core files - if you do, when you upgrade WP, your change will be lost. – anu Jul 11 '12 at 17:11
-1 for hacking core. See the accepted answer. – Chris_O Jul 12 '12 at 7:00
-10000 for hacking core. Don't hack core, even if you find no other solution (which is highly unlikely) – kovshenin Dec 10 '12 at 18:57
That 0.01 second timeout is there for a reason! The WP-cron call happens in the background and you don't want your code to halt on that. And also: you never hack into core files! – dhuyvetter May 18 at 8:15
