I dont know if is a bug or some problem with my server but this message is going with me on almost every installation of WordPress and has to do with a silly function: wp_schedule_single_event($unix_time_stamp, ‘publish_future_post’, array($post_ID)).
I hope this plugin solves many people with the same problem. I tested for almost a week and is working fine and publishing everything that needs to be published.
Ok, enough of the mumble jumbo, here is the plugin:
Just unzip in your “wp-content/plugins” folder, activate the plugin and that’s it.
