Maximum performances for a better SEO Some WordPress plugins slow down the websites that use them. Contact Manager has been developed with a lot of attention to its performances so that it doesn’t slow down your website and it remains fast. Moreover, contrary to a common practice among WordPress plugins/themes, Contact Manager doesn’t add any CSS or JavaScript files to the pages of your website, in order to not increase their weights or the number of HTTP requests. So even after installing this plugin, your website’s pages will still load as quickly as before, and their Google PageSpeed scores will not drop.

Spam is expensive: it wastes time, clogs inboxes, creates fake accounts, and on stores it can lead to abandoned checkout noise and fraudulent activity. Traditional CAPTCHA solutions can also hurt conversions by adding friction. Cloudflare Turnstile is a modern, privacy-first CAPTCHA alternative designed to reduce friction for real people while still blocking bots. Kitgenix CAPTCHA for Cloudflare Turnstile is a production-ready Turnstile integration for WordPress that focuses on reliability in real-world setups: – Server-side token verification (using Cloudflare’s official endpoint) – Fast, conditional loading (only where needed) – Support for dynamic/AJAX forms and modern WooCommerce Blocks / Store API checkout – Security features: replay protection, proxy-aware IP handling, whitelisting, and developer mode (warn-only) You can enable/disable each integration (and many per-form toggles), choose auto-injection vs shortcode-only placement, customise display and messaging, and use built-in diagnostics and Site Health checks to troubleshoot. The plugin also includes a real setup-verification gate for sensitive flows, a Portability tab for JSON export/import, a Support tab with active protection alerts, per-integration analytics, CSV exports, privacy-safe metrics, and recent verification events, and support for defining keys through wp-config.php constants or environment variables. Supported integrations (where Turnstile can be added) All integrations are enable-able from settings. Many also support Mode: Auto vs Shortcode.

Define KITGENIX_CAPTCHA_FOR_CLOUDFLARE_TURNSTILE_SITE_KEY and KITGENIX_CAPTCHA_FOR_CLOUDFLARE_TURNSTILE_SECRET_KEY in wp-config.php or your environment when you want keys managed outside the database. Manual placement (shortcode) If you have a custom form or an unsupported plugin, you can manually render the widget: [kitgenix_turnstile] Shortcode output includes: – a nonce field – a hidden cf-turnstile-response input – the widget container (with data-sitekey) – support for passing arbitrary attributes via shortcode attributes Many supported integrations also offer Shortcode-only mode (you place the shortcode where you want; the plugin validates server-side without auto-injection). Quick Start Install and activate the plugin. Open the Turnstile settings under the Kitgenix hub in wp-admin. Add your Cloudflare Turnstile Site Key and Secret Key. Configure widget options (theme/size/appearance/language) and messaging if needed. Enable the integrations (and per-form toggles) you want. Save, then test the key user journeys: login, registration, checkout, and your main contact form. Tip: Start with Developer mode (warn-only) on staging or during rollout. Once you’re satisfied, disable warn-only to enforce blocking. Performance and caching notes (important for stores) Turnstile is lightweight, but aggressive optimisation can break rendering or token freshness. If you use caching/optimisation plugins: – Allowlist https://challenges.cloudflare.com – Avoid full-page caching on login/account/checkout pages – Avoid combining/inlining the Turnstile loader – Avoid heavily delaying Elementor/form plugin scripts – Ensure outbound HTTP requests to Cloudflare are not blocked (needed for server-side verification) Settings Overview Main settings: – Site Key – Secret Key (with “secret present” state, clear/reveal) – Theme (auto/light/dark) – Size (normal/compact/flexible) – Appearance (Turnstile appearance option) – Language (auto or specific locale) – Disable submit until completed – Custom error message – Extra message text Security & advanced: – Replay protection (on/off) – Developer mode (warn-only) – Whitelist logged-in users – Whitelist IPs (wildcards/CIDR, including IPv6) – Whitelist user agents – Proxy trust (enable/disable) – Trusted proxy IPs / trust controls – Setup verification before sensitive rollouts Portability & operations: – Export settings to JSON – Import settings from JSON – Optionally include or exclude site keys during transfer – Support KITGENIX_CAPTCHA_FOR_CLOUDFLARE_TURNSTILE_SITE_KEY and KITGENIX_CAPTCHA_FOR_CLOUDFLARE_TURNSTILE_SECRET_KEY as constants or environment-variable overrides for keys Integrations (enable + per-form toggles where available): – WordPress Core (login/register/lost password/reset password/standard comments) – WooCommerce (checkout/product reviews/login/register/lost password) – WooCommerce Blocks mode (auto vs shortcode-only) – Easy Digital Downloads (checkout/login/register/profile) – Contact Form 7 – WPForms – Fluent Forms – Formidable Forms – Forminator – Gravity Forms – Jetpack Forms – Kadence Forms – Elementor Forms – bbPress – BuddyPress Developers Shortcode: [kitgenix_turnstile] Server-side verification endpoint: https://challenges.cloudflare.com/turnstile/v0/siteverify Filters (script/loading): – kitgenix_captcha_for_cloudflare_turnstile_script_url( $url, $settings ) – kitgenix_turnstile_freshness_ms – kitgenix_turnstile_inline_style Filters (verification / request handling): – kitgenix_turnstile_siteverify_url – kitgenix_turnstile_siteverify_timeout – kitgenix_turnstile_siteverify_sslverify – kitgenix_turnstile_siteverify_http_args – kitgenix_turnstile_send_remoteip – kitgenix_turnstile_remote_ip – kitgenix_turnstile_token_from_request – kitgenix_turnstile_handle_comment_form – kitgenix_turnstile_error_codes – kitgenix_turnstile_error_message – kitgenix_turnstile_replay_message – kitgenix_captcha_for_cloudflare_turnstile_{context}_turnstile_error_message Filters (replay protection): – kitgenix_turnstile_replay_ttl Filters (operational alerts): – kitgenix_turnstile_alert_window_seconds – kitgenix_turnstile_alert_failure_spike_min_failures – kitgenix_turnstile_alert_failure_spike_failure_rate – kitgenix_turnstile_alert_http_error_min_failures Filters (whitelist / proxy trust): – kitgenix_turnstile_is_whitelisted( $is_whitelisted, $details ) – kitgenix_turnstile_trust_headers – kitgenix_turnstile_trusted_proxies Internal identifiers (options / transients / cookies / meta): – Option: kitgenix_captcha_for_cloudflare_turnstile_settings – Settings group (Settings API): kitgenix_captcha_for_cloudflare_turnstile_settings_group – Option: kitgenix_captcha_for_cloudflare_turnstile_metrics – Option: kitgenix_turnstile_recent_event_log – Option: kitgenix_turnstile_last_verify – Transient: kitgenix_captcha_for_cloudflare_turnstile_do_activation_redirect – Transient: kitgenix_turnstile_duplicate_scripts – Transient prefix (replay protection): kitgenix_captcha_for_cloudflare_turnstile_ts_ – Cookie (replay notice): kitgenix_captcha_for_cloudflare_turnstile_ts_replay – WooCommerce order meta (Blocks/Store API verification): _kitgenix_turnstile_verified Internal nonces / actions: – Shortcode/form nonce field name: kitgenix_captcha_for_cloudflare_turnstile_nonce – Shortcode/form nonce action: kitgenix_captcha_for_cloudflare_turnstile_action – Settings save nonce field name: kitgenix_captcha_for_cloudflare_turnstile_settings_nonce – Settings save nonce action: kitgenix_captcha_for_cloudflare_turnstile_settings_save – Admin AJAX action (reveal saved secret): kitgenix_turnstile_get_secret (WordPress hook: wp_ajax_kitgenix_turnstile_get_secret) – Admin AJAX nonce action (reveal saved secret): kitgenix_turnstile_reveal_secret – Admin-post action (analytics exports): kitgenix_turnstile_export_analytics – Admin-post nonce action (analytics exports): kitgenix_turnstile_export_analytics – Duplicate-loader notice dismiss query arg: kitgenix_captcha_for_cloudflare_turnstile_ts_dismiss_dupe – Duplicate-loader notice dismiss nonce action: kitgenix_captcha_for_cloudflare_turnstile_ts_dismiss Actions (developer logging): – kitgenix_turnstile_dev_log External Services This plugin uses Cloudflare Turnstile to verify requests and prevent spam and abuse. The plugin may: – Load the Turnstile script: https://challenges.cloudflare.com/turnstile/v0/api.js – Submit verification requests server-side to: https://challenges.cloudflare.com/turnstile/v0/siteverify When verification is enabled, the plugin sends to Cloudflare: – Your Turnstile secret key – The Turnstile response token – The visitor IP address (as the optional remoteip parameter, when enabled) The plugin does not send the visitor’s browser user agent to Cloudflare as part of the verification payload (the HTTP request itself is made server-side by WordPress). If proxy trust is enabled, the plugin may read forwarding headers (e.g. CF-Connecting-IP, X-Forwarded-For) to determine the client IP, but only when requests originate from configured trusted proxies. The plugin does not add tracking cookies itself and does not sell or share personal data. Cloudflare Turnstile Terms: https://developers.cloudflare.com/turnstile/ Cloudflare Privacy Policy: https://www.cloudflare.com/privacypolicy/ This plugin also includes a shared “Kitgenix hub” component in wp-admin which may fetch publicly available plugin metadata from WordPress.org using the WordPress core plugins_api() function (WordPress.org Plugins API). When it runs: only in wp-admin (Kitgenix plugin admin pages) Data sent: plugin slug(s) (no personal data) Data received: publicly available plugin information (e.g. active installs, ratings) Caching: responses are cached locally using transients for ~1 day: kitgenix_hub_wporg_active_installs_v1 kitgenix_hub_wporg_ratings_v1 Trademark Notice “Cloudflare” and the Cloudflare logo are trademarks of Cloudflare, Inc.
