This is How to Fix the 'Load More Posts with AJAX' Not Working Issue in WordPress
One of the most frustrating issues WordPress developers can face is when the 'Load More Posts with AJAX' feature suddenly stops working on their website. Users expect a smooth, seamless experience when navigating through your content, and a broken infinite scroll can severely impact your site's user experience and engagement metrics.
Unfortunately, there's no single, universal fix for this problem, as the root cause can vary depending on your WordPress setup, theme, plugins, and even server configurations. However, in this comprehensive guide, we'll dive deep into the common reasons why 'Load More Posts with AJAX' might not be working and provide you with tried-and-tested solutions to get it up and running again.
Understanding the 'Load More Posts with AJAX' Functionality
The 'Load More Posts with AJAX' feature allows users to load additional content on your WordPress website without having to refresh the page. This is achieved by using AJAX (Asynchronous JavaScript and XML) to dynamically fetch and display new posts or content as the user scrolls down the page.
This functionality is particularly useful for blogs, e-commerce sites, and other content-heavy websites, as it enhances the user experience by providing a more seamless and engaging browsing experience. Instead of forcing users to navigate through multiple pages, the 'Load More Posts with AJAX' feature allows them to continuously scroll through your content, which can lead to increased time on site, reduced bounce rates, and potentially better conversion rates.
Common Reasons Why 'Load More Posts with AJAX' Isn't Working
Before we dive into the solutions, let's first explore the most common reasons why the 'Load More Posts with AJAX' feature might not be working on your WordPress website:
-
Theme or Plugin Conflicts: Your WordPress theme or a conflicting plugin may be interfering with the AJAX functionality, causing it to break or not work as expected.
-
JavaScript Errors: Issues with your website's JavaScript, such as syntax errors or missing dependencies, can prevent the AJAX requests from being made correctly.
-
Server Configuration Issues: Problems with your web server's configuration, such as PHP or caching settings, can also lead to the 'Load More Posts with AJAX' feature not working as intended.
-
Incomplete or Incorrect AJAX Implementation: If you've implemented the AJAX functionality yourself, there may be errors or oversights in your code that are causing the issue.
-
WordPress Core Updates: Sometimes, updates to the WordPress core can introduce compatibility issues with the 'Load More Posts with AJAX' feature, especially if you're using a custom implementation or a third-party plugin.
Now that we've identified the most common causes, let's dive into the solutions to fix the 'Load More Posts with AJAX' not working problem on your WordPress website.
Solution 1: Check for Theme or Plugin Conflicts
The first step in troubleshooting the 'Load More Posts with AJAX' issue is to check for potential conflicts with your WordPress theme or plugins. These conflicts can arise when your theme or a plugin is interfering with the AJAX functionality or overwriting the necessary JavaScript code.
To identify and resolve any theme or plugin conflicts, follow these steps:
-
Deactivate and Switch to a Default Theme: Temporarily switch your WordPress website to a default theme, such as Twenty Twenty-One or Twenty Twenty-Two, to see if the issue persists. If the 'Load More Posts with AJAX' feature starts working after switching to the default theme, it's likely that your current theme is the culprit.
-
Deactivate Plugins One by One: Systematically deactivate your plugins, one by one, to see if the issue is resolved. This will help you identify the specific plugin that's causing the conflict. Once you've identified the problematic plugin, you can either update it, configure it correctly, or replace it with an alternative solution.
-
Check for Conflicting AJAX-related Plugins: Some plugins, such as caching, optimization, or infinite scroll plugins, may have their own AJAX functionality that could interfere with the default 'Load More Posts with AJAX' feature. Ensure that you don't have any conflicting plugins installed and activated on your website.
-
Update Plugins and Themes to the Latest Version: Outdated plugins or themes can sometimes cause compatibility issues, so make sure to keep everything up to date. This includes your WordPress core, themes, and plugins.
By following these steps, you should be able to identify and resolve any theme or plugin-related issues that are causing the 'Load More Posts with AJAX' feature to stop working.
Solution 2: Fix JavaScript Errors
If the issue persists after ruling out theme and plugin conflicts, the next step is to check for and fix any JavaScript errors that might be interfering with the AJAX functionality.
To troubleshoot JavaScript errors, follow these steps:
-
Inspect the Browser Console: Open your web browser's developer tools (usually by pressing F12 or right-clicking and selecting "Inspect") and navigate to the "Console" tab. Here, you'll be able to see any JavaScript errors or warnings that are being generated on your website.
-
Identify and Fix the Errors: Look for any error messages in the console and try to understand what they mean. Common JavaScript errors include syntax errors, missing dependencies, or conflicts with other JavaScript code on the page. Address these errors by correcting the code or removing the conflicting scripts.
-
Ensure jQuery is Properly Enqueued: The 'Load More Posts with AJAX' feature often relies on the jQuery library, so make sure it's properly enqueued in your WordPress theme or plugin. You can do this by adding the following code to your functions.php
file:
function my_theme_scripts() {
wp_enqueue_script('jquery');
}
add_action('wp_enqueue_scripts', 'my_theme_scripts');
-
Disable Minification or Concatenation: If your website is using a caching or optimization plugin that minifies or concatenates your JavaScript files, try disabling these features temporarily to see if the issue is resolved.
-
Check for Conflicting JavaScript Libraries: Ensure that there are no other JavaScript libraries or frameworks (such as Prototype or MooTools) that could be interfering with the jQuery-based AJAX functionality.
By addressing any JavaScript-related errors or issues, you should be able to resolve the 'Load More Posts with AJAX' not working problem on your WordPress website.
Solution 3: Optimize Server Configuration
In some cases, the issue with the 'Load More Posts with AJAX' feature may be related to your web server's configuration. Problematic server settings, such as caching or PHP settings, can prevent the AJAX requests from being processed correctly.
To optimize your server configuration, consider the following steps:
-
Check Caching Settings: If you're using a caching plugin or a web server-level caching solution (such as Varnish or Nginx), ensure that AJAX requests are not being cached. Caching AJAX responses can lead to the 'Load More Posts with AJAX' feature not working as expected.
-
Increase PHP Memory Limit: WordPress and its plugins may require more memory than the default PHP memory limit allows. Try increasing the memory limit by adding the following line to your wp-config.php
file:
define('WP_MEMORY_LIMIT', '256M');
-
Ensure PHP is Configured Correctly: Make sure that your PHP version is up-to-date and that the necessary PHP extensions are enabled. This includes extensions like curl
, xml
, and json
, which are often required for AJAX functionality.
-
Check for Firewall or Security Rules: If your web server is behind a firewall or has security rules in place, ensure that they are not blocking or interfering with the AJAX requests.
-
Optimize Database Performance: A slow or inefficient database can also impact the AJAX functionality. Consider optimizing your WordPress database by running regular maintenance tasks, such as clearing the cache, optimizing tables, and removing unused data.
By addressing any server-related issues, you can help ensure that the AJAX requests are being processed correctly, which should resolve the 'Load More Posts with AJAX' not working problem.

If you're using a custom implementation of the 'Load More Posts with AJAX' feature, it's essential to verify that the code is correctly implemented and optimized for performance.
Here are some steps to help you troubleshoot and improve your AJAX implementation:
-
Review the AJAX Callback Function: Ensure that the AJAX callback function is properly handling the server's response and updating the DOM with the new content. Check for any syntax errors or logical issues in the function.
-
Validate AJAX Requests: Make sure that the AJAX requests are being sent correctly and that the server is responding with the expected data. You can use browser developer tools or tools like Postman to test the AJAX endpoint.
-
Optimize AJAX Performance: Minimize the amount of data being sent and received by the AJAX requests. Only send the necessary data, and avoid sending large payloads or unnecessary information.
-
Implement Error Handling: Add robust error handling to your AJAX implementation, so that users are informed of any issues and the feature can gracefully handle failures.
-
Leverage Caching Strategies: If appropriate, consider implementing client-side or server-side caching strategies to improve the performance and responsiveness of the 'Load More Posts with AJAX' feature.
-
Test on Different Browsers and Devices: Ensure that the AJAX functionality works consistently across different browsers, devices, and network conditions.
By thoroughly reviewing and optimizing your AJAX implementation, you can address any underlying issues and ensure that the 'Load More Posts with AJAX' feature is working as expected.
