We have got you covered. With our step-by-step guide, you will learn how to quickly fix this error, ensuring smooth functionality and uninterrupted Ajax requests on your WordPress site. So let’s get started!
Common Causes of WordPress Ajax Error
When encountering a WordPress Ajax error, there could be several factors contributing to the issue. It’s important to understand the common causes so that you can efficiently troubleshoot and resolve the problem. The most common causes of WordPress Ajax errors are plugin conflicts, theme conflicts, and server issues. Let’s take a closer look at each of these causes.
Plugins are a crucial component of any WordPress website, but sometimes they can clash with each other, resulting in an Ajax error. This conflict occurs when two or more plugins try to utilize the same Ajax functionality simultaneously. To determine if a plugin conflict is at the root of the issue, you’ll need to follow some troubleshooting steps.
Themes play a significant role in the appearance and functionality of a WordPress site. However, some themes may have incompatible or poorly coded Ajax functionality, leading to conflicts. If you suspect a theme conflict is causing the Ajax error, you’ll need to undertake specific troubleshooting steps to identify and resolve the issue.
Server-related problems can also contribute to Ajax errors on your WordPress site. These issues usually arise from misconfigurations or limitations within the server environment. Troubleshooting server issues requires a bit more technical knowledge, but there are steps you can take to pinpoint and resolve the problem.
Now that we’ve identified the common causes of WordPress Ajax errors, let’s delve into the troubleshooting steps that can help you resolve these issues. By following these steps, you’ll be able to identify the specific cause of the Ajax error and take the necessary actions to fix it.
Check for Plugin Conflict
To tackle plugin conflicts, start by disabling all plugins on your WordPress site. Then, gradually reactivate them one by one, testing the Ajax functionality after each activation. By doing this, you can identify the specific plugin that is causing the conflict.
Switch to a Default Theme
If you suspect a theme conflict, switch to a default WordPress theme, such as Twenty Twenty-One. Once you have activated the default theme, check if the Ajax error persists. If the error disappears, you can be confident that the issue lies with your previously active theme.
Test with Another Server
Sometimes, server issues can be the culprits behind Ajax errors. To rule out server-related problems, you can test your WordPress site on another server. If the Ajax error is not present on the new server, it’s a clear indication that your original server is causing the issue.
Increase PHP Memory Limit
Inadequate PHP memory can also contribute to Ajax errors. To address this, you can increase the PHP memory limit on your WordPress site. This can be done by modifying the
wp-config.php file or by contacting your hosting provider for assistance.

Fixing Plugin Conflict
When you’ve identified a plugin conflict as the cause of the Ajax error, it’s time to take the necessary steps to resolve the issue. Follow these steps to fix the plugin conflict and restore the functionality of your WordPress site.
Disable Plugins Temporarily
To fix the plugin conflict, you’ll first need to temporarily disable all the plugins on your site. This will allow you to isolate the problematic plugin causing the Ajax error.
Identify the Problematic Plugin
Once you have disabled all the plugins, gradually enable them one by one. After each activation, test the Ajax functionality to see if the error reappears. By enabling and testing each plugin individually, you can identify the specific plugin causing the conflict.
Update or Replace the Plugin
Once you have identified the problematic plugin, check for any available updates. Developers frequently release updates that can fix compatibility and functionality issues. If an update is available, install it and test the Ajax functionality. However, if no update is available or the issue persists, consider replacing the plugin with an alternative that offers similar features.
Fixing Theme Conflict
In the case of a theme conflict causing the Ajax error, specific steps need to be taken to resolve the issue. Follow these steps to fix the theme conflict and restore the Ajax functionality on your WordPress site.
Activate a Default WordPress Theme
To address a theme conflict, switch to a default WordPress theme, such as Twenty Twenty-One. This eliminates any potential conflicts caused by your previously active theme.
Identify the Conflict-Causing Theme
Once you have activated the default theme, test the Ajax functionality. If the error disappears, the issue lies with your previous theme. To identify the conflict-causing theme, revert to your original theme and deactivate all plugins except for the ones required by the theme. Test the Ajax functionality again to determine if the error reoccurs.
Consult the Theme Developer
If you have identified the theme causing the conflict, contact the theme developer for support. Explain the Ajax error you encountered and provide them with any relevant error messages or details. The theme developer will be able to provide guidance or a fix to resolve the conflict and restore the Ajax functionality.

Resolving Server Issues
Server-related problems can be more complex to troubleshoot and resolve, but with the right steps, you can tackle them effectively. Follow these steps to address server issues causing Ajax errors on your WordPress site.
Check Server Logs
To begin resolving server issues, start by checking the server logs. These logs can provide valuable insights into any errors or misconfigurations occurring on the server. Look for any error messages related to Ajax functionality, as they can help identify the cause of the issue.
Contact Hosting Provider for Support
If you are unable to resolve the server issue on your own, it’s recommended to reach out to your hosting provider for support. They have technical experts who can investigate the server configuration and identify any issues causing the Ajax error. Provide them with detailed information, including the steps you have taken and any error messages you have encountered.
Optimize Server Configuration
In some cases, optimizing the server configuration can resolve Ajax errors. This may involve adjusting server settings, updating software, or allocating more resources to your WordPress site. Consulting with your hosting provider or a server administrator can help you determine the appropriate optimizations needed for your specific server environment.
Optimizing WordPress AJAX
Optimizing the usage of Ajax in your WordPress site can help prevent or minimize Ajax errors. By following these best practices, you can ensure a smooth and efficient Ajax functionality.
Reduce AJAX Calls
Carefully evaluate the Ajax calls on your site and ensure that they are necessary. Minimizing the number of Ajax calls can reduce the chances of encountering errors and improve overall performance.
Minimize the Amount of Data Sent
When making Ajax requests, it’s essential to send only the necessary data. Minimizing the amount of data being sent can improve the efficiency and speed of your Ajax functionality.
Optimize Code and Queries
Review your code and database queries involved in the Ajax functionality. Optimize them by eliminating unnecessary code, improving query performance, and implementing caching mechanisms where appropriate. This can significantly enhance the speed and reliability of your Ajax functionality.

Updating WordPress and Plugins
Keeping your WordPress core and plugins up to date is crucial for both security and functionality. Regularly updating these components can fix bugs, patch security vulnerabilities, and improve overall performance. Follow these steps to ensure that your WordPress site is always running on the latest versions.
Check for Updates
Periodically check for updates on your WordPress site. This includes both WordPress core updates and plugin updates. Developers frequently release new versions that address known issues and improve functionality.
Update WordPress Core
Start by updating your WordPress core to the latest available version. Before performing the update, it’s recommended to create a backup of your site to prevent any potential issues during the update process. Once the backup is done, proceed with updating the WordPress core.
After updating the WordPress core, it’s essential to update your plugins as well. Visit the “Plugins” section in your WordPress dashboard and check for any available updates. Update each plugin individually, ensuring compatibility and functionality improvements.
Clearing WordPress Cache
Caching is a mechanism used to store and deliver pre-generated content, improving the performance of your WordPress site. However, cached data can sometimes cause conflicts and errors. Clearing the WordPress cache can help resolve such issues.
Use Cache Plugins
If you have cache plugins installed on your WordPress site, you can utilize their built-in cache clearing options. These plugins often provide easy-to-use functionality to clear the cache and ensure that your site’s content is up to date.
Clear Browser Cache
In addition to clearing the WordPress cache, it’s also important to clear your browser cache. Browsers often store static files to enhance page loading speed. However, outdated cached files can lead to conflicts and errors. Clearing your browser cache ensures that you are loading the most recent version of your site.
Reset Object Cache
If you are utilizing an object caching mechanism, such as Memcached or Redis, resetting the cache can help resolve conflicts and errors. Consult the documentation or support resources for the specific caching mechanism you are using to learn how to reset the cache.

As errors occur, your website generates log files that record important information about the errors. These logs can provide valuable insights into the cause of Ajax errors. Accessing and reviewing these error logs is a crucial step in the debugging process.
Analyze Error Messages
When debugging Ajax errors, error messages are your best friends. Analyze the error messages thoroughly to understand the specific nature of the problem. Often, error messages contain clues regarding the file, line number, or function causing the issue, which can help in resolving it.
