Enable jQuery Migrate Helper


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.


  1. Upload to your plugins folder, usually wp-content/plugins/.
  2. Activate the plugin on the plugin screen.
  3. That’s it! The plugin handles the rest automatically for you.


What does it mean that something is “deprecated”

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.

How do I find and use the browser console

WordPress.org has an article about using the browsers console log to diagnose JavaScript errors.

Both WpBakery and the Theme had issues. This fixed everything. Thanks a million for this awesome plugin!

Wouldnt it be possible to throw a warning if a Theme uses this function and/or to suggest installing this plugin when one has problems? I am not a developer and spent hours and had no idea why slider revolution is not working anymore. Then I tried to use the slider from visual composer and had no success as well. That pointed me in the direction it has to be some jquery related stuff so I could use google correctly. But it stole more time of the day than necessary.
