My future posts are getting "missed". They are not getting published on the time they should, and it says "Missed Schedule".

I read somewhere that it could be a server issue, so how can I fix it?

Try the Missed Schedule plugin. – hsatterwhite Mar 31 '11 at 23:53
I found a plugin that was recently updated and used that. Since there was only a small code, I didn't install the pluging, but used the code in my functions-file. – Martin-Al Apr 2 '11 at 19:45

Added the following to my theme's functions.php:

define('WPMS_DELAY', 5);  // Run the below cron task every X minutes
define('WPMS_OPTION', 'wp_missed_schedule');

function wpms_replacements_deactivate() {
register_deactivation_hook(__FILE__, 'wpms_replacements_deactivate');

// Run the following code on every request
function wpms_init() {
    remove_action('publish_future_post', 'check_and_publish_future_post');
    $last = get_option(WPMS_OPTION, false);

    // Exit here if less than WPMS_DELAY minutes has passed since we last ran
    if (($last !== false) && ($last > (time() - (WPMS_DELAY * 60))))

    // Find all posts whose scheduled time has passed and publish them
    update_option(WPMS_OPTION, time());
    global $wpdb;
    $scheduledIDs = $wpdb->get_col("
        SELECT `ID` FROM `{$wpdb->posts}`
        WHERE (
          ((`post_date` > 0) && (`post_date` <= CURRENT_TIMESTAMP()))
          OR ((`post_date_gmt` > 0) && (`post_date_gmt` <= UTC_TIMESTAMP()))
        AND `post_status` = 'future'
        LIMIT 0, 10
    if (!count($scheduledIDs)) 
    foreach ($scheduledIDs as $scheduledID) {
        if (!$scheduledID) continue;
add_action('init', 'wpms_init', 0)

Could you explain what this actually does? – Vince Pettit Apr 10 '13 at 10:03
