4 min read

A newly published fact suggests WordPress 5.5.1 has an adverse impact on thousands of websites. Removing a major and vastly used tool will eventually interrupt your websites. In this article, we will discuss why WordPress 5.5.1 is breaking
the websites and the solution to this problem.

Modification in WordPress 5.5.1

There are so many tools in WordPress that make our work way more comfortable. However, a migration tool named as jQuery -migrate is no longer available in the updated version of WordPress 5.5.1. Making changes in libraries such as jQuery
can be a lot of work; in this case, jQuery-migrate makes it easy. This tool could make many codes run despite being a deprecated jQuery code. This tool made sure that it re-established deprecated properties and behavior so that the code
will work properly on the present or later jQuery model.

Why was jQuery Migrate removed from WordPress 5.5.1?

There have been many disagreements from plugins and themes, causing many websites to fall apart. But the main question is, why did WordPress 5.5.1 decide to remove jQuery Migrate. To make sure the plugins and themes are not outdated and are
not using any questionable codes, removing jQuery Migrate was the most initial and essential step. As it is well known that WordPress always tries to use updated features, so it is more convenient to remove jQuery Migrate. By getting rid of
it, there will be one less JavaScript for the portal to obtain and perform, and it will also reduce the avoidable load from your server.

What happens after updating the WordPress 5.5.1?

any outdated codes, which lead to the breaking of websites.

This is one kind of temporary solution to this problem. As with the updating version of WordPress 5.5, the jQuery-Migration will no longer be working, so installing this jQuery-Migrate helper plugin will help support the outdated codes and
give the developer or author the time to improve the codes. You can install this by going to the WordPress dashboard to see Add new under the plugin option. Then you can find a jQuery-Migrate helper and install it.

  • Search for the warnings given by the jQuery-Migrate helper plugin While you are using WordPress administration, there will be warnings but not on the websites’ front end. You need to check the browser console. Here you will
    find the warnings.
  • Updating themes and plugins As the themes and plugins are outdated, they will create a version update to install. After this, when there will be no warnings, the plugins will be updated, you can deactivate the jQuery-Migrate
    helper plugin.
