The JTC Anti-Spam|Anti-Hacker hover tooltip animation no longer worked after upgrading to WordPress 5.5. This problem was caused by the wp-jquery-lightbox plugin. Cause of the problem was that the wp-jquery-lightbox plugin enqueued jQuery in the footer instead of the header. The plugin author has been notified about this issue/problem > https://wordpress.org/support/topic/jquery-being-enqueued-in-footer-instead-of-head/
A workaround solution until the plugin author has time to fix this issue/problem:
Edit this wp-jquery-lightbox plugin file > /wp-content/plugins/wp-jquery-lightbox/wp-jquery-lightbox.php
Change this code:
wp_enqueue_script('jquery', '', array(), false, true);
To this code:
wp_enqueue_script('jquery', '', array(), false, false);
