Fix for Chartboot and WP 4.0

Edit the charbootforwordpress.php file

add the line
wp_enqueue_script( 'jquery-ui-dialog' );
to the function LPCFW_EquequeScripts

The whole function should look like this:

function LPCFW_EquequeScripts() {

        wp_register_script( 'custom-script', plugins_url( '/js/custom.js', __FI$
        wp_enqueue_script( 'custom-script', array('jquery-ui'));
        wp_enqueue_script( 'jquery-ui-dialog' );
        wp_enqueue_style (  'wp-jquery-ui-dialog');

}
