About this plugin
ClassicFlare does one thing: it keeps the copy of your site that Cloudflare holds at the edge in
step with your content. Publish, update or trash a post, approve a comment, and the pages that
changed are purged from Cloudflare, along with every page that shows them.
- Posts and pages: the permalink, and the old one too when the slug changes
- Everything that lists the post: the homepage and its first pages, category, tag, date,
author and post type archives
- Comments: a new approved comment, or one approved, unapproved, spammed or trashed
- Feeds: the site feed, the comments feed, each post’s comment feed and each archive’s feed,
in RSS2, Atom and RDF
- Sitemaps: read from the index your site publishes, so the right files are cleared, from
core, Yoast SEO, Rank Math, All in One SEO or SEOPress
- Media, categories, tags, menus and theme changes, each with its own switch
- A list of extra paths, such as /llms.txt, purged alongside every automatic purge
- “Purge this page” and “Purge everything” in the toolbar, and a button on the settings screen
- A retry when Cloudflare is rate limiting or unreachable, honouring Retry-After, for only the
URLs that failed
- Works with plain and pretty permalinks
- A public API and WP-CLI commands for deploy scripts
It does not change anything in your Cloudflare zone: no cache rules, no zone settings, no page
rules. It only ever asks Cloudflare to forget cached files.
ClassicFlare is built for ClassicPress 2 and works the same on WordPress. It is not affiliated
with or endorsed by Cloudflare, Inc. or the ClassicPress project.
External services
The plugin talks to one outside service, the Cloudflare API, to clear the copy of your pages that
Cloudflare holds. Nothing else leaves your server: no update checker, no licence check, no
analytics.
Cloudflare API (https://api.cloudflare.com/client/v4/)
Only contacted once you have configured an API token. Without one, nothing is sent.
What it sends, and when:
- Your API token, as an authorization header on every request.
- When you press Connect or Test connection: a token verification request, your site’s hostname
to find the matching zone, and your zone identifier.
- The URLs to purge, in batches of up to 30, whenever content changes on your site (a post
published, updated or deleted, a comment approved, a term or menu edited, the theme switched),
when you press a purge button, when a WP-CLI purge runs, and when a purge that failed is
retried.
It never sends visitor data, personal data or post content.
Cloudflare, Inc. provides the service. Their terms and privacy policy:

Requests to your own site
To learn which sitemap files exist, the plugin reads your own sitemap index twice a day, on
WP-Cron. That request goes to your own site and involves no third party.
What the plugin stores
No custom tables. Settings live in the options table: one small autoloaded option, plus a few
that only load on the settings screen (the token, the zone details, the extra paths, the
sitemap list and the result of the last purge). WP-Cron refreshes the sitemap list and runs
retries.
Turning on “Delete data on uninstall” removes all of it when you delete the plugin. Leave it off
and nothing is removed, so deactivating to debug a conflict does not cost you your configuration.
Credits
0-or-later. ClassicFlare is derived from Oh My Cache! by Butiá Labs, keeping only
its Cloudflare integration. That code in turn reimplemented ideas from App for Cloudflare by
org/plugins/app-for-cf/) and Nginx Helper by rtCamp
com/rtCamp/nginx-helper). Nothing third party is bundled.
