Out of the blue, my post scheduling ceased working a couple a days ago.

I tried everything I found when looking for the answer here at Wordpress Answers, but none of the suggestions worked in my case.

Could anyone offer a solution for this? I'm running the latest Wordpress version and already tried disabling the plugins.

Thank you

Has this stopped working completely or is it off by a few hours? Did you make any changes/updates to any files before this happened? – Zach Russell Apr 6 '13 at 17:39
Zach, the scheduling had stopped completely, but the problem was solved. Please see the solution with the comment below. Thanks for asking. – user31002 Apr 7 '13 at 10:16

If you are caching (parts of) your site, manually or via a plugin (such as WP Super Cache, for instance), it might have a negative impact on the functionality of wp_cron.
If done via a plugin, disabling it might not suffice, as WP Super Cache for example does not clear the page cache it has created upon deactivation.

If you want to keep caching active, a solution might be to setup a manual Cron Job for the php file /wp-cron.php

You do realize wp_cron is a pseudo-cron, not a real-time deamon, and apart from the name has no connection with Unix Cron Jobs whatsoever?! – Johannes Pille Apr 6 '13 at 18:30
What I meant was that the wp-cron.php is missing the ping and a Cron Job can be created to do so. This can happen with cache plugins caching the cron file. – Naveen Narale Apr 6 '13 at 18:51
Aight. Now your answer does make much more sense to me. Though if the OP indeed tried having all plugins disabled while a scheduled post was meant to be published and a user visited the site after the scheduled time, then I suppose caching plugins could not be responsible. – Johannes Pille Apr 6 '13 at 19:08
If the OP is using WP Super Cache and has deactivated it, it does not clear the page cache it has created. Also, after deactivation, it is no longer able to delete any expired pages. – Naveen Narale Apr 6 '13 at 21:39
I have limited experience with that particular plugin. If that's the case with it (and others of the same kind) though, why not expand your answer by those explanations you have given in the comments? – Johannes Pille Apr 6 '13 at 21:51
