Why would I need this plugin?

Do you need to manually clear your server-side caches everytime you modify your site, what about automating it, or need to do it in CLI? If yes, then this is for you.

How do I utilize the CLI cache clearing?

Shell into your server and run the command wp the_cache purge. Please note that if you are a root user, you may need to add the --allow-root argument. Also note, that if yout site is a network, you will need to add the url argument for the site you want to purge… --url=http(s)://

This plugin, in tandem with WP Rocket on hosting (Business Plan), does a deeper and more effective purge of my site’s cache. Sure, WP Rocket has its own purge, but it does not go as deep. This plugin really does assist in making things right. Thank you 🙏

I have been using this plugin for over 18 months and it does eactly what it says on the tin! About 4 weeks ago It stopped working due to server upgrades on my web hosting platform. The developer was very quick to respond to my issue and helped me through a minefield to the point where it is once again working. If you need your Cache purged on a regular basis…look no further
