What Changes in WordPress 5.5 Are Causing Your Site to Break?
WordPress 5.5 update comes with many new features such as lazy loading images, auto-updates, the default XML Sitemaps, and more. However, certain changes in the new version are causing sites to break. One of the significant changes is – jQuery Migrate turned off by WordPress 5.5.
WordPress 5.5 removed jQuery Migrate which was available in WordPress for many years to help WordPress plugins and themes with outdated code still run optimally. By removing jQuery Migrate, many outdated plugins and themes are not working properly, leading to broken websites.
What is jQuery Migrate?
Why Did WordPress 5.5 Turn Off jQuery Migrate?
Outdated versions of jQuery are not supported anymore, and therefore, WordPress needs to update coding standards. As WordPress prepares to move to update to the latest supported version of jQuery, removing jQuery Migrate was a primary step to ensure plugins and themes are up-to-date and not using deprecated code anymore.
Why Does My Site Break After Updating to WordPress 5.5?
It’s simple. You may be using a plugin or theme with outdates code. When you update to WordPress 5.5, outdated plugins or themes will no longer run properly.
Since WordPress core no longer supports the old code base of plugins or themes, it may break your site.
How to Fix Broken Site After Updating to WordPress 5.5?
If you’ve updated your website and need to fix your broken website, we advise you to create a complete backup of your website first. However, if you have less expertise in the technical stuff, it is always best to hire a WordPress developer having strong expertise and experience in WordPress website development.
If you’re experiencing a broken site after updating to WordPress 5.5, here are a few steps you can take to fix your broken site.
1. Download & install the jQuery Migrate Helper plugin
The first thing you need to do is, install the jQuery Migrate Helper plugin on your WordPress site. This plugin will re-enable the jQuery Migrate tool that was turned off in WordPress 5.5, and provide you with details about which plugin or theme might not be functioning properly.
However, the jQuery Migrate Helper Plugin is just a temporary solution and should not be used as a long-term solution for fixing your site. After installing and activating the jQuery Migrate Helper plugin, you will see a message to explain that you’ll see warning while using your WordPress admin, however, they will not be displayed on the front-end of your site.
2. Look for warnings given by the jQuery Migrate Helper plugin in your WP admin area
The jQuery Migrate Helper Plugin will produce a list of pages in your WP admin that have issues in WordPress 5.5 with an error message. The error message will indicate which plugin(s) may be causing problems.

3. Find additional errors using your browser console
The plugin will also produce output error messages in your browser console to help you detect which plugin or theme has broken your WordPress website. Troubleshooting this way to diagnose errors is a bit more technical. Make sure you hire a WordPress developer to help you fix the issue.
4. Keep all your plugins and themes up-to-date
If you get warning messages, make sure you check the theme or plugin that generated those messages for a version update. There might be an update that you can install.
If you find that you’re running an outdated version of a theme or plugin, update it to the latest version. Available updates will be displayed in your WordPress admin panel on the Updates page.
If you’re using an old version of a premium plugin or theme, you will need to add your license key or purchase a new license to update to the newer version. Many premium plugins and themes use license keys to offer updates through your WordPress admin dashboard. So, you should see any available updates after adding a license key.
However, if you’ve opted for PSD to WordPress conversion, you must get your codebase reviewed by a WordPress website development company for any bugs, faults, or loopholes.
5. If you find no updates, contact the theme or plugin developer to update their code
If you want to continue using one of the themes or plugins with outdated code, you need to contact the theme or plugin developer to update their code. If you get no response, you will need to remove the outdated plugin or theme entirely as the code will not be functional in newer versions of WordPress.
Potential Security Issues that Come with Outdated Plugins and Themes
As a WordPress security best practice, it is good to keep your themes and plugins up-to-date. New versions often include security patches and updates for security vulnerabilities, so you need to update everything.
The security risk of running outdated plugins and themes has become a critical issue that WordPress 5.5 now resolves with auto-updates for plugins and themes. So, it is always a good idea to turn auto-updates on and get a WordPress backup plan in place.
Why There’s a Need to Back Up Your WordPress Site?
Before updating to any major version of WordPress, you must create a complete backup of your site. As the latest WordPress 5.5 version introduces additional changes like auto-updates of plugins and themes, it’s always a good idea to have a solid WordPress backup.
Running outdated plugins or themes is the first reason why WordPress sites get hacked. Plugins and themes with old code pose a serious security risk to your WordPress site. Therefore, we strongly advise users not to use outdated plugins and themes that have been abandoned by their developers.
