WordPress Version 5.5 is Breaking Plugins

After installing the latest WordPress version 5.5, many websites are experiencing problems with number of installed plugins, including Classic Editor, WP Bakery, and Yoast. These plugins happen to be among some of the most popular and widely-installed WordPress plugins. Following the installation of WordPress 5.5, certain features of the website have stopped working on a number of websites.

How to Fix WordPress version 5.5 Issues On Your Website

We have found a temporary workaround that will fix the broken plugins in WordPress, simply install the WordPress plugin: Enable jQuery Migrate Helper.

According to the plugin developers:

“With the update to WordPress 5.5, a migration tool known as jquery-migrate will no longer be enabled by default. This may lead to unexpected behaviors in some themes or plugins who run older code. This plugin serves as a temporary solution, enabling the migration script for your site to give your plugin and theme authors some more time to update, and test, their code”

With the addition of this plugin, you will likely see a series of warnings about deprecated files  in WordPress administration, but these will not be shown or affect the front-end of your site. A script, a file, or some other piece of code is deprecated when its developers are in the process of replacing it with more modern code or removing it entirely.

This solution is temporary, but it should restore your website’s features until additional updates are available from WordPress and the plugin developers. Enable jQuery Migrate Helper is open source software and was developed in part by WordPress.org.
