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”
On the next page you should see the “Purge” and “Flush” buttons. The “Purge” button will clear static files from our CDN while “Flush” will remove page cache from our server.
You can read more about the levels of caching in Pressable to know the difference between the caching setups.
