Cron Job
You may ask why I need to add a cron job when there is a cache timeout feature.
The Cache Timeout feature works with WP Schedule which works when someone visits your WordPress site. If your site doesn’t receive a lot of traffic, WP Schedule may not work properly so you need to add a cronjob.
wget -O - "https://www.YOUR-URL.com/?action=wpfastestcache&type=clearcache&token=123abc" >/dev/null 2>&1
