Diagnosing jQuery Version Conflicts in WordPress Responsive Menus

When these sites run on WordPress, developers frequently encounter issues where custom responsive menu toggle scripts, designed to work with a specific jQuery version, collide with the jQuery version bundled by the active theme or a plugin.
