TL;DR

AI summary of the plugin's readme

This plugin is for WordPress site administrators dealing with themes or plugins that rely on older jQuery code. It re-enables the jQuery Migrate script and allows temporarily downgrading jQuery so outdated theme or plugin code keeps working while authors update it.

Frequently Asked Questions

Common questions about Enable jQuery Migrate Helper

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.

With the release of WordPress 5.6, the jQuery version also gets updated. This means that plugins or themes that previously caused deprecation warnings now instead will cause errors. This plugin will allow you to, temporarily, return to the previous version of jQuery if this happens (it will also try to do so automatically for website visitors the first time an error happens) allowing you to fix the code, or replace it.

WordPress.org has an article about using the browsers console log to diagnose JavaScript errors. The plugin isn't logging deprecations or changing jQuery versions If your site has any plugins for combining JavaScript files, or loading them asynchronously, this plugin may be negatively affected and not be able to operate as intended. If your site requires this plugin to operate, please disable any plugins which interact with the loading of JavaScript files such as the types mentioned above. Once the underlying issue has been resolved, you may remove this plugin and re-enable those other tools.

If something isn’t working correctly on your site after you upgraded WordPress, then you can simply try installing and activating this plugin. If this helps, then you leave this plugin activated and follow the instructions in the plugin. The plugin will tell you when you don’t need it any more. There are a lot of deprecation warnings when using jQuery version 3 As jQuery version 3 is very new to WordPress, this is expected. Deprecated notices means that the Migration tool is in place making sure these features still continue working while the related code is updated.
