//This is how to set up a cron job via PHP in WordPress.

// The issue: 
// You want to use WP Bakery for your WooCommerce shop page. 
// You can enable WP Bakery for that page, but custom Design Options are not showing.

// The explanation:
// WP Bakery keeps those custom design changes as a CSS string, stored as post meta on the page you are using for your shop page.
// Unfortunately that CSS is not being output by your theme, hence your custom design changes are not working.
