What is WordPress Missed Schedule Error?
The WordPress missed schedule error happens when a scheduled post doesn’t publish at the time you’ve set. Typically, WordPress uses an internal task scheduler called WP-Cron to handle actions like publishing scheduled posts. But if WP-Cron doesn’t trigger correctly—often due to low traffic or server delays—WordPress may fail to publish the post on time. Instead, it remains stuck with a “Missed Schedule” status in your Posts list. While you can manually publish it afterward, this error can interrupt your editorial flow and defeat the purpose of scheduling content in advance.
Why Does WordPress Fail to Publish Scheduled Posts?
WordPress uses cron jobs to automate tasks like publishing scheduled posts. In UNIX-based systems, these tasks—known as crons or schedulers—run commands or scripts at specific times without manual input.
However, the WordPress cron system isn’t a true cron. It’s a simulated or “faux” cron system that doesn’t run on the server level. Instead of being triggered by a timer, WordPress crons depend on website traffic. When someone visits your site, WordPress checks if there are any scheduled tasks to run.
This workaround exists because many web hosting environments don’t allow access to system-level cron settings. While it’s a clever solution, it has a downside: if no one visits your site around the scheduled time, your post might not get published—leading to the WordPress missed schedule error.
For instance, if you set a post to go live at 11:00 p.m. but your site has low traffic and no visits occur at that time, the post won’t publish, and you’ll see a missed schedule WordPress error.
Even on high-traffic websites, the WordPress schedule system can fail. If too many visits trigger cron jobs too frequently, it can lead to server strain or conflicts with caching plugins—both of which can prevent scheduled posts from going live.
Additionally, if your site experiences temporary downtime, or your caching plugin interferes with cron execution, you may encounter missed schedule posts even with adequate traffic.
- Troubleshooting WordPress Scheduled Post Not Publishing:
- If you find that your WordPress schedule post isn’t being published as expected, here are some common areas to check:
- Plugin Conflicts – Disable caching or optimization plugins temporarily.
- Check WP-Cron Status – Ensure DISABLE_WP_CRON is not set to true in your wp-config file.
- Use a Real Cron Job – Consider setting up a server-level cron via your hosting dashboard.
- Install a Fix Plugin – Use plugins like “WP Missed Schedule” to automatically handle these errors.
- By understanding how WordPress schedules posts and what causes errors, you can proactively ensure reliable publishing.
Steps to Troubleshoot WordPress Missed Scheduled Error
1. Check Your Timezone Settings
Incorrect timezone configuration can cause scheduled posts to be missed. Since WordPress uses the server’s time to publish posts, the posts won’t publish at the scheduled time only if there’s a discrepancy between the time on the server and the timezone settings on your website.
To change your timezone, go to Settings>>General from your WordPress dashboard. Scroll down to the “Timezone” section and choose the city closest to your location or select the UTC offset that matches your local time. Then click Save Changes.
2. Clear the WordPress Cache
Clearing the WordPress cache is one important maintenance step that can help fix several problems, include WordPress missed scheduled posts error. WordPress caching plugins save static versions of your website to improve performance and loading times and optimize speed of the website. However, these cached data can occasionally cause problems with planned tasks when they become outdated or damaged.
It’s important to clear your cache regularly to prevent issues. The process to clear the cache differs depending on the cache plugin you are using.
- If you are using WP Super Cache, navigate to your WordPress dashboard, then go to Settings > WP Super Cache > Delete Cache to clear your cache.
- For W3 Total Cache, go to Performance > Dashboard > Empty All Caches.
- If you are using WP Rocket, go to Settings > WP Rocket > Clear Cache.
Once you clear the cache, you can try scheduling a sample post to see whether it works. You can also set your cache plugins to prevent it from interfering with your scheduled posts. Here are some tips to do that:
- Add wp-cron.php to the excluded list to ensure the cron jobs can run without interference. Most plugins allow you to exclude specific URLs from caching.
- Set a shorter cache expiration time, so the pages are refreshed more often, allowing scheduled posts to publish as intended.
- Regularly clear your cache to ensure that it does not hold outdated content.
3. Increase the WordPress Memory Limit
A low memory limit can affect how your website performs in all activities, including publishing scheduled posts. It even worsens when resource-demanding plugins are active or during heavy traffic.
You can give WordPress extra resources to handle these activities effectively by raising the memory limit. To do this, you must access your wp-config.php file via cPanel or an FTP client.
Note: It is best to back up WordPress before altering your wp-config file. Just to be safe. Here’s our guide on backuping your WP files.
If you are using cPanel, navigate to File Manager>> Public_html folder. Then scroll down to locate the WPconfig.php file. Once you find the file, right-click on it and click on Edit.
Now add the code below before the line that says; ‘That’s all, stop editing! Happy publishing.’
define(‘WP_MEMORY_LIMIT’, ‘500M’);
And that’s it. You have successfully increased your memory limit.
You can try to publish a sample post to see if it works.
If none of these troubleshooting measures work, then it’s time to move on to more permanent methods for fixing WordPress missed schedule errors.
Alternative Methods To Fix Missed Schedule Error Permanently
There are four ways to fix a WordPress missed schedule error. If one method doesn’t fix the problem, try the next.
Method 1: Install A Plugin to Fix WordPress Missed Schedule Error
One easy way to fix the WordPress missed schedule error is to use a plugin. There are WordPress plugins out there to prevent missed schedules, like Scheduled Post Trigger and WP Scheduled Post plugins for this illustration.
i. Use Scheduled Post Trigger to fix WordPress Missed Schedule Error
Scheduled Post Trigger has over 70,000 active installs and is compatible with WordPress version 3.0.1 and higher. Once installed, this plugin checks if there are any missed scheduled posts. If it finds any missed posts, it publishes them immediately.
To install the Scheduled Post Trigger plugin, go to Plugins>>Add New from your WordPress dashboard
Type ‘Scheduled Post Trigger’ in the search bar (at the top-right corner of your screen) and click Install Now.
Once the installation is complete, click Activate.
And that’s all! You don’t need to configure the plugin. Once it’s activated, you no longer need to worry about missing scheduled posts.
If you install this plugin and your scheduled posts still go unpublished, check your time settings. Ensure your time zone is set correctly, or set it as I explained earlier. Also, watch out for plugin conflicts. You can do this by turning off your other installed plugins one after the other to identify the conflicting ones.
Ii. Use WP Scheduled Post Plugin to Solve WordPress missed schedule error
WP Scheduled Post is another incredible plugin to help you take care of your missed schedule. This plugin offers you three other functions, which include:
- Managing your content with a visual calendar.
- Creating schedules for your posts.
- Automatically share your WP posts on social media.
It is compatible with WordPress version 4.0 and higher.
To use this plugin, go to Plugins >> Add New from your dashboard. Next, type the name of the plugin, “WP scheduled post,” in the search bar. Once you find it, click ‘install now’ and then activate.
Once you activate the plugin, it will publish any missed scheduled posts on your website. The plugin also allows you to schedule your new posts and view all the posts on a calendar.
That’s all for this method. Plugins for WordPress are very helpful pieces of software. We have compiled a list of the best WordPress plugins every WP site owner must have. You should check it out.
Plugins can help resolve missed schedule errors, but they need to be kept up-to-date and compatible with your site’s setup. With WordPress website maintenance plans, you can ensure that all your plugins, including those managing post schedules, are maintained and updated regularly.
Method 2: Check Your wpconfig.php File
Sometimes, the WP cron may have been disabled, and that could be the reason why WordPress isn’t publishing your scheduled posts. To know if your WP cron is disabled, check your WPconfig.php file.
To locate the WPconfig.php file, log into your cPanel (most hosting providers will give you access to your cPanel). Alternatively, you can access your files using FTP.
Using cPanel, go to File Manager>> Public_html folder. Scroll down and locate the WPconfig.php file.
Right-click on the wp-config.php file and select ‘edit’. Check if the file has this line of code;
define (‘DISABLE_WP_CRON’, true);
If it does, it means WP cron is disabled on your site. To enable it, simply delete this line and save your changes. And that should fix the issue.
If you do not see the line of code, then cron was enabled, and you should try the next fix.
Method 3: Disable Default WP Cron and Enable Alternate Cron
This method works most of the time, especially if your server settings conflict with your WP crons. All you need to do is disable the default WP cron. And then go ahead and enable an alternative one.
To do this, you have to edit your wpconfig.php file to include two new lines of code. As I stated earlier, you can find the wp-config file by logging into your cPanel or FTP. And then go to File Manager >> Public_html folder.
Once you find it, right-click on the file and select edit. Paste these lines of code at the bottom, just before the line that says “stop editing, happy blogging”:
define(‘DISABLE_WP_CRON’, true);
define(‘ALTERNATE_WP_CRON’, true);
And that should fix your missing schedule error in WordPress. You should test if this procedure worked by scheduling a post.
Method 4: Replacing WP-Cron with a Real Server-Side Cron Job
This method is a bit more technical than the first three methods. If you are comfortable working with your server, then you should use this method. It’s a permanent way to fix the ‘missed schedule errors’.
Once you complete this process, you’ll be using real crons to trigger WP schedules (instead of faux crons). Here’s how it’s done.
Step 1: Disable WordPress Cron to prevent any conflict.
To do this, log into your cPanel and open the file manager >> public_html folder. Scroll down in search of the wp-config.php file. When found, click ‘edit’. Next, add the following line of code at the bottom of the file and save changes.
define(‘DISABLE_WP_CRON’, true);
And that’s it. You have successfully disabled the WordPress cron.
Step 2: Implement manual crons
The next step is to implement manual crons through your server again. To do this log in to your cPanel and scroll to the advanced section. You’ll sthis,ee ‘Cron Jobs’. Click on it.
To add a new cron job, scroll to the add new cron job section. First, you need to set how often you want cron events to take place.
To do this, click on the ‘Common Settings’ dropdown and pick an option that suits you.
If you set a 5-minute interval, it means your cron will trigger WP cron every 5 minutes. That could be overbearing on your server. As such, it is best to give a wider interval between cron events, like twice per hour, or even once per hour.
Step 3: Input cron command
Next, you need to input the cron command that should be run. You can do this by pasting the following line of code in the input box labeled ‘Command’:
wget -O /dev/null http://yourwebsite.com/wp-cron.php?doing_wp_cron
Don’t forget to replace ‘yourwebsite’ in the code with the actual name of your site.
Example: wget -O /dev/null https://fixrunner.com/wp-cron.php?doing_wp_cron
Finally, click ‘Add New Cron Job’ to finish the process.
Now WordPress won’t miss any of your scheduled posts since you no longer depend on WP faux crons but on real crons.
Use a third-party Cron Service
If your hosting provider doesn’t offer the option to create custom cron jobs, then you should consider using third-party cron services like EasyCron or FastCron. These third-party services can handle the execution of WordPress cron jobs externally, bypassing server limitations.
To use EasyCrone, you need to first disable the WP Cron System by editing your wp-config.php file and adding the following code to it:
define(‘DISABLE_WP_CRON’, true);
Once you are done, open your EasyCron dashboard and click on the + Cron Job button.
Input the crone command wget -O /dev/null http://yourwebsite.com/wp-cron.php?doing_wp_cron in the “URL to call” field (replace yourwebsite your website).
Choose an appropriate cron job execution frequency. For WordPress post schedules, we recommend setting the cron job to run every 30 minutes or 1 hour.
Complete any other optional settings if necessary.
Click the Create Cron Job button, and you’re done. EasyCron will trigger your WordPress schedule cron job command to ensure your post publishes at the specified time.
Note: Most managed WordPress hosting can help you configure your cron. See a compilation of the best WordPress hosting providers.
One of these methods would likely work for you and resolve your missed scheduled post issue. However, it is still important to manually check your scheduled posts and publish any failed posts. To do this, go to Posts > All Posts in your WordPress dashboard, and filter by Scheduled to see upcoming posts. Then manually publish any posts that have missed their scheduled time.
