@crusehh: WordPress 3.6 uses jQuery version 1.10.2. See this in your site http://mmghealth.com/wp-includes/js/jquery/jquery.js?ver=1.10.2
So, this is not a theme or plugin issue. Either you need to change your map to Google Map or you need to add new version of jQuery through Google CDN. For that you need to build child theme and add the following Code in your child theme functions.php
function catchchild_jquery_enqueue() {
if ( !is_admin() ) {
wp_deregister_script( 'jquery' );
wp_register_script( 'jquery', 'http://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js', false, '2.0.3' );
wp_register_script( 'jquery', "http" . ($_SERVER['SERVER_PORT'] == 443 ? "s" : "") . "://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js", false, null);
wp_enqueue_script( 'jquery' );
}
}
add_action( 'wp_enqueue_scripts', 'catchchild_jquery_enqueue' );
For more please take help from WordPress Support Forum as this is not a theme or plugin issue.
