At CanadaCreate, we prioritize the safety and security of our website visitors. Keeping jQuery updated is essential for maintaining both the security and functionality of your website.

When we inform our readers about website security, we cannot stress enough how important it is to perform updates promptly.

Using an outdated version of jQuery can expose your site to security vulnerabilities, create compatibility problems with themes and plugins, and potentially lead to site crashes.

In this article, we will guide you through the process of updating jQuery to the latest version in WordPress, ensuring that your site remains stable, secure, and optimized for performance.

Reasons to Upgrade jQuery to the Latest Version in WordPress

Your WordPress website, along with many of the plugins and themes you utilize, depends on JavaScript and jQuery to deliver fast, interactive, and engaging features.

Keeping jQuery updated is crucial for the security of your website. The latest version addresses bugs and vulnerabilities found in earlier versions that could jeopardize your site.

If you are using the latest version of WordPress, jQuery will be updated automatically, so no manual action is required. However, if you are on an older version of WordPress, such as 5.4 or earlier, it is advisable to perform the update.

If you’ve replaced the default WordPress jQuery with the Google Library, it will not automatically update to the latest version.

Note from the Editor:It’s essential to understand that updating jQuery might disrupt the functionality of older plugins. After the update, be sure to test your website. Generally, this isn’t a problem, but if you encounter issues, you can easily revert to the previous version.

How to Check if Your jQuery Version Is Outdated

You can easily check the version of jQuery your website is using by accessing the JavaScript console in your web browser.

First, visit your website and open the JavaScript console. If you’re using Google Chrome, you can do this by selectingView » Developer » JavaScript Consolefrom the menu.

Next, paste the following command into the console:

jQuery.fn.jquery

This command will show you the current version of jQuery that your website is using.

Ideally, you should see version 3.5.1 or later. If your website is using a version that starts with 1.7 or lower, it is strongly recommended to upgrade.

Method 1: Upgrade jQuery to the Latest Stable Version

The jQuery Updater plugin allows you to update jQuery to the latest official stable version, which is likely to be newer than the version bundled with WordPress.

Begin by installing and activating the jQuery Updater plugin. For detailed instructions, refer to our comprehensive guide on how to install a WordPress plugin.

Once activated, your website will use the latest version of jQuery. You may need to clear your browser and WordPress cache to see the updates take effect.

The plugin includes the jQuery Migrate script to ensure backward compatibility. If you experience issues with any plugins, you can easily deactivate the jQuery Updater plugin to revert your site to its previous state.

Method 2: Manage the Version of jQuery Running on Your Website

The Version Control for jQuery plugin enables you to manage the jQuery version used on your website. This feature helps WordPress users maintain a stable site, while developers can test their code against different jQuery versions.

To begin, install and activate the jQuery Updater plugin. For assistance, refer to our detailed guide on how to install a WordPress plugin.

Once activated, the plugin will automatically use the latest pre-release version of jQuery. It also includes the jQuery Migrate script to ensure backward compatibility.

If necessary, you can choose a different version of jQuery by navigating to the Settings » jQuery Version Control page.

Here, you can select the jQuery and jQuery Migrate versions you want to use on your site. Remember to click the ‘Save Changes’ button to apply your settings.

If the new jQuery version causes issues with your older plugins, you can easily revert to a previous version using the drop-down menu. Additionally, deactivating the Version Control for jQuery plugin will restore your site to its original configuration.
