Description (last modified by kawauso)

The cron loop existing on cron.php in the wp-includes does not work.

The wp_cron() shows code that doesn't re-lists recurring events and does not fire any event. There is no other code firing those events.

This code is calling for a "callback" array element that is not set on the scheduler array.

After checking wp-cron.php, and adapting the code from that to wp_cron(), now everything works as it should.

Changed function looks like:

 * Run scheduled callbacks or spawn cron for all scheduled events. Adapted from wp-cron.php
 * @since 2.1.0
 * @return null When doesn't need to run Cron.
function wp_cron()

    // Prevent infinite loops caused by lack of wp-cron.php
    if (strpos($_SERVER['REQUEST_URI'], '/wp-cron.php') !== false || (defined('DISABLE_WP_CRON') && DISABLE_WP_CRON))

    if (false === $crons = _get_cron_array())

    $local_time = time();
    $keys = array_keys($crons);

    if (isset($keys[0]) && $keys[0] > $local_time)

    foreach ($crons as $timestamp => $cronhooks) {
        if ($timestamp > $local_time)

        foreach ( (array)$cronhooks as $hook => $keys) {

            foreach ($keys as $k => $v) {

                $schedule = $v['schedule'];

                if ($schedule != false) {
                    $new_args = array($timestamp, $schedule, $hook, $v['args']);
                    call_user_func_array('wp_reschedule_event', $new_args);

                wp_unschedule_event($timestamp, $hook, $v['args']);

                do_action_ref_array($hook, $v['args']);
