This article covers how to easily fix the missed schedule post error in WordPress. WordPress scheduled posts not publishing can be resolved by using a plugin such as "WordPress cron jobs" to help trigger scheduled posts to publish your WordPress Post.
Cron is a technical term for commands that run on a scheduled time, like your scheduled posts in WordPress.
Technically, a real cron job will run at the server level. But because WordPress doesn't have access to that level, it runs a simulated cron.
These simulated cron jobs, like scheduled posts, are supposed to be triggered whenever a person or bot visits your site.
But because it's not a real cron job, sometimes it causes a missed schedule error.
TO FIX THE MISSED SCHEDULE ERROR IN WORDPRESS:
Every fifteen minutes the post scheduler plugin checks for posts that have the missed schedule error, and will automatically publish them for you.
Multiple techniques for checking your site's missed posts are used to make sure a scheduled post is not missed.
Methods to fix the WordPress missed schedule error:
1. Use the Scheduled Post Trigger plugin.
2. Manage cron jobs directly through your server.
