How to Disable wp-cron in WordPress and Set Up Proper Cron Jobs

Hi there, fellow WordPress enthusiasts! As a seasoned WordPress developer with over 15 years of experience under my belt, I’ve encountered numerous situations where the default wp-cron system falls short. That’s why I’m excited to share with you this comprehensive guide on disabling wp-cron and setting up robust, reliable cron jobs.

If you’re experiencing issues with scheduled actions like missed post publications, delayed emails, or other time-sensitive tasks, it’s likely because the default wp-cron system isn’t cutting it. Unlike a true cron job, which is handled by your server’s operating system, wp-cron relies on website visits to trigger its execution. This can lead to inconsistencies, especially for websites with low traffic.

In this article, we’ll walk through the process of disabling wp-cron and setting up proper cron jobs, ensuring your scheduled tasks run smoothly and reliably. We’ll cover two primary methods, along with a bonus tip for automating post scheduling.

Why Disable wp-cron?

Let’s delve deeper into the limitations of wp-cron:

• **Triggered by Website Visits:** wp-cron relies on website visits to trigger its execution. This means if your website has low traffic, scheduled tasks might not happen on time. Conversely, high traffic can result in frequent wp-cron checks, impacting performance.
• **Inconsistent Scheduling:** Due to its reliance on user visits, wp-cron can be unreliable. If your server is busy or experiencing downtime, tasks could be delayed or missed altogether.
• **Performance Impact:** Frequent wp-cron checks can strain your server resources, especially on high-traffic sites, leading to slower loading times and a less enjoyable user experience.

The bottom line is, while wp-cron works for many sites, it’s not the most reliable or efficient solution. For optimal performance and consistency, proper cron jobs are the way to go.

Disabling wp-cron in WordPress

Let’s begin by disabling wp-cron. This is a simple process requiring just a single line of code in your wp-config.php file. Here’s how to do it:

1. Make a Backup: Before editing any core WordPress file, always create a backup of your wp-config.php file. This safeguards you against any accidental errors.
2. Access wp-config.php: Use an FTP client or your web hosting control panel’s file manager to access the wp-config.php file located in the root directory of your WordPress installation.
3. Add the Code: Paste the following code into your wp-config.php file just before the line that says “That’s all, stop editing! Happy blogging.”

   define('DISABLE_WP_CRON', true);

4. Save and Upload: Save the changes to your wp-config.php file and upload it back to your server.

That’s it! WordPress will now stop using wp-cron. However, you’ll need to set up proper cron jobs to ensure your scheduled tasks continue to run.

Method 1: Setting Up a Proper Cron Job on Your WordPress Host

The most straightforward way to establish proper cron jobs is using your WordPress hosting provider’s tools. This method usually involves using the cPanel interface, which is commonly provided by web hosting providers.

Here’s a step-by-step guide using Bluehost’s cPanel (note that the specific steps might vary slightly depending on your hosting provider):

1. Log into cPanel: Log in to your hosting account and locate the cPanel interface. You’ll usually find a link to cPanel in your hosting control panel.
2. Navigate to Cron Jobs: Look for the “Cron Jobs” section within cPanel. This might be located in the “Advanced” tab or another relevant section.
3. Create a New Cron Job: Click on the “Add New Cron Job” button. You’ll be presented with a form where you can define the cron job’s settings.
4. Schedule the Cron Job: Choose how often you want the cron job to run. A common frequency is every 30 minutes. cPanel provides various options like “Twice Per Hour,” “Once Per Day,” and more. Select the option that best suits your needs.
5. Enter the Command: Paste the following command into the “Command” field. Make sure to replace “example.com” with your website’s URL.

   wget -q -O - https://example.com/wp-cron.php?doing_wp_cron >/dev/null 2>&1

6. Save the Cron Job: Click on the “Add New Cron Job” button to save your settings. The newly created cron job will be added to the list, ensuring your scheduled tasks run regularly.

By setting up a cron job using this method, WordPress will now check for and execute scheduled tasks based on the schedule you defined (in this case, every 30 minutes), rather than relying on user visits.

Method 2: Setting Up a Proper Cron Job Using a Third-Party Service

If your hosting provider doesn’t offer cron job functionality or if it’s difficult to use, you can leverage third-party cron services. These services provide a user-friendly interface for creating and managing cron jobs, regardless of your hosting provider.

Here are some well-regarded third-party cron services:

• EasyCron: EasyCron offers a free plan (requiring monthly renewal) that’s perfect for basic needs. It’s known for its simplicity and user-friendliness.
• cron-job.org: A free service with a range of features, making it a popular choice for managing cron jobs.
• Cronitor: Provides a free tier for a single cron job. Ideal for users who need a basic cron job solution without paying for a full subscription.
• SetCronJob: Offers paid plans starting at $10 per year. If you need more advanced features or have multiple cron jobs, SetCronJob is an excellent option.

Let’s go through the process of setting up a cron job using EasyCron (a free service):

1. Create a Free Account: Sign up for a free account on EasyCron. The free plan allows you to get started quickly and easily.
2. Create a New Cron Job: Click the “+ Cron Job” button to create a new cron job. You’ll be presented with a straightforward form.
3. Enter the URL: Paste the following URL into the “URL to call” field, replacing “example.com” with your website’s URL:

   https://example.com/wp-cron.php?doing_wp_cron

4. Schedule the Cron Job: Select “Every 30 minutes” from the “When to execute” dropdown. You can customize the schedule based on your specific requirements.
5. Save the Cron Job: Click the “Create Cron Job” button to store your settings. The newly created cron job will be added to your EasyCron dashboard, ready to run every 30 minutes.

Now, you have a reliable cron job set up using a third-party service. This ensures your scheduled actions are executed on time and consistently.

Bonus: Auto-Schedule Your WordPress Blog Posts

With proper cron jobs in place, your scheduled WordPress tasks will function flawlessly. This opens up exciting opportunities, such as automating blog post scheduling. Here’s how to do it:

1. Install PublishPress Planner: Install and activate the PublishPress Planner plugin, which is designed to simplify and enhance post scheduling.
2. Configure Content Calendar: Navigate to the “Planner » Settings” page and switch to the “Content Calendar” tab. Enable the “Scheduled” option under “Statuses to display publish time.” This allows you to view scheduled posts on the calendar.
3. Set Default Publish Time: Select a time format for your post publications and click on the field next to “Default publish time for items created in the calendar.” This will open a prompt where you can choose the specific hour and minute for your scheduled posts to be published daily.
4. Schedule Posts in the Block Editor: When creating or editing a post, select “Scheduled” from the “Post Status” dropdown in the block editor. This will allow you to set a specific publication date and time for your post.

By using PublishPress Planner, you can effortlessly schedule posts to be published automatically at the desired time, leveraging the power of your cron jobs. This saves you time and ensures your content reaches your audience consistently.
