How to include iframeResizer.min.js script

Hey norwestarch,
To add a script to your WP site you will need to upload it and adjust this function so the path is correct and add it to your functions.php:

function my_custom_scripts() {
    wp_enqueue_script(
        'custom-script',
        get_stylesheet_directory_uri() . '/js/my_custom.js',
        array( 'jquery' )
    );
}

I see that you are not using a child theme, I would point out that without using a child theme your customizations will be lost on the next update.
Please use our pre-built child theme
You will want to take a couple of steps, 1: please export your theme settings at: Enfold Theme Options > Import/Export > Export Theme Settings File to your computer, this is just for backup.
2: Once you install your child theme, please import your parent theme settings at:
Enfold Theme Options > Import/Export > Import Settings from your Parent Theme
Then you’ll need to re-set your menu options.
Finally, sometimes it is necessary to save your theme options one more time, to encourage the settings to be saved and activated in the merged /wp-content/uploads/dynamic_avia/ folder, a simple way to do this is to go to General Styling > Quick CSS field and place a space in the field so the theme options “Save all changes” button is clickable.

Best regards,
Mike
