With the update to WordPress 5.5, a migration tool known as <code>jquery-migrate</code> was no longer enabled by default. This may lead to lacking functionality or unexpected behavior in some themes or plugins that 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 update to WordPress 5.6, the included version of jQuery is also upgraded. This means that old code that previously caused warnings now may instead may cause errors or stop working entirely.
Some of the features no longer working will just stop working behind the scenes without any apparent problem.
The plugin will let you downgrade to a previous version of jQuery for a period, but as a site administrator you are encouraged to get the underlying issue fixed.

Also lets you know when it's no longer needed!!!!

This is what I call going above and beyond. I would rate 10 stars if I could. You deserve it.

Love it, super simple - perfect solution

WordPress has a built-in feature to install themes and plugins by supplying a zip file. Unfortunately, you cannot upgrade a theme or plugin using the same process. Instead, WordPress will say “destination already exists” when trying to upgrade using a zip file and will fail to upgrade the theme or plugin.
Easy Theme and Plugin Upgrades fixes this limitation in WordPress by automatically upgrading the theme or plugin if it already exists.
While upgrading, a backup copy of the old theme or plugin is first created. This allows you to install the old version in case of problems with the new version.
Attention: Version 2.0.0 changed the functionality of the plugin. You are no longer required to select “Yes” from a drop down before the theme or plugin can be upgraded. The need for an upgrade is now detected automatically. So, if you are used to the old functionality of the plugin, do not be concerned about the absence of upgrade details on the theme and plugin upload pages. Simply upload the theme or plugin as if you were installing it, and the plugin will automatically handle upgrading as needed.

This is a great plugin, and works exactly as intended.

Works great!


This was a GREAT plugin and I used it for years, but WordPress core does this now, so the plugin is no longer needed.  Thank you for your great work all these years.


No longer needed

Easily upgrade your themes and plugins using zip files without removing the theme or plugin first.
