Posted this in another thread about table sorting issues I was having. Here's what I added to that thread describing what fixed my problem:
I had a problem with my file data table not sorting via the column headers. I fixed the issue by loading an older version of jQuery. I'm running WP 4.3 and it was loading jQuery 1.11.3. I was getting a jQuery error in the console so I added the following to my functions.php file where I am enqueueing scripts to load up 1.11.2 and that fixed my issues. Hope this works for the rest of you. I even tried loading some 2.0 version and some of them worked too but I decided to stick with one version older than what 4.3 was loading.
function my_scripts_method() {
wp_deregister_script('jquery');
wp_register_script('jquery', 'https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js', false, '1.11.2');
}
add_action('wp_enqueue_scripts', 'my_scripts_method', 99);
