Enable jQuery Migrate Helper is a free WordPress plugin designed to assist users facing compatibility issues after the removal of the jQuery migration tool in WordPress 5.5. This plugin temporarily reactivates the migration script, allowing themes and plugins that rely on older jQuery code to function correctly while developers update their software. It is particularly useful for site administrators who may notice missing functionality or unexpected behaviors due to outdated code in their themes or plugins.

The plugin also provides the option to downgrade to a previous version of jQuery, which can help maintain site stability during the transition period. However, it is important to note that while this plugin offers a workaround, site administrators are strongly encouraged to address the underlying issues with their themes and plugins to ensure long-term compatibility with newer versions of WordPress.
