Thanks a ton Venutius. That did the trick. Never thought of that. Sometimes the solution can be so simple…

Thanks again!

Are you looking to load a more up to date version of jquery?

Exactly.

This is the whole code I am using:

function replace_core_jquery_version() {
  wp_deregister_script( 'jquery' );
  wp_register_script( 'jquery-new', get_template_directory_uri() . '/js/jquery.min.js', array(), '3.3.1', true );
  wp_deregister_script( 'jquery-migrate' );
  wp_enqueue_script('jquery-new');
}
add_action( 'wp_enqueue_scripts', 'replace_core_jquery_version' );
