This plugin will purge the entire cache at GraphCDN and/or Cloudflare on create/edit of posts, pages, menu items and attachments.
- Upload the files to
/wp-content/plugins/ - Enter any settings on the plugins settings page. You don't need to set both Cloudflare and GraphCDN, just the one provider you need or both.
Getting cookies to work with GraphCDN is a little tricky. You'll want to make sure your PHP constant COOKIE_DOMAIN is set to a .example.com. A lot of WordPress hosts (like Flywheel) prevent you from setting COOKIE_DOMAIN on your own though. See here for our solution.
