There are multiple options for purging and flushing site caches here at Pressable. Note that your site may temporarily encounter degraded performance after a cache flush.

MyPressable Control Panel Cache Controls

To clear the WordPress object cache or purge the CDN, login to the MyPressable Control Panel and select the site you want to purge the cache for by clicking on “Settings”

From the “Cache” tab you can selectively purge and flush the Edge Cache (CDN) and Object Cache.

WP-CLI Cache Flush Command

Another option for flushing your site cache is via WP-CLI.

Once connected to your site via SSH, the following WP-CLI commands can be utilized to flush the site’s caches.

  • Object cache: wp cache flush
  • Edge cache for the entire site: wp edge-cache purge --domain
  • Edge cache for specific URL(s): wp edge-cache purge "https://samplesite.com/path" "https://samplesite.com/path?get=param"

Pressable Cache Management Plugin

The Pressable Cache Management plugin can also be installed on your site to allow you to manage Batcache, Edge Cache and Object Cache from your site’s WP Admin Dashboard.
