This plugin allows you to display a form when users click on links inside of elements with a class you specify. The plugin uses a custom version of jQuery UI on the front end, and does not address situations where Javascript is turned off. It does provide a simple, attractive contact form inside of a modal dialog box.

This plugin updates <a href="http://jquery.com/" rel="nofollow ugc">jQuery</a> to the latest official stable version, which is most likely not available within the latest stable release of WordPress. 
jQuery Migrate is also included for backwards compatibility.
No files are replaced, therefore deactivation of this plugin returns your site to it`s original state.
Since WordPress 5.6 includes an up-to-date version of jQuery 3, upgrading shouldn’t`t be necessary in most cases.
Warning
If you are not familiar with beta testing, bugfixing, javascript or running bleeding edge software it`s not recommended. 
I will not provide help on JavaScript and jQuery, only on plugin related issues (PHP)!
Reporting problems
Please post bug reports and request for help on <a href="https://wordpress.org/support/plugin/jquery-updater" rel="ugc">WordPress.org Support Forums</a>.
