About this plugin
php should probably be disabled”? But every time you end up in a forum thread with 12 conflicting code snippets, three of which will wreck your site.
WebsiteFix One-Click Optimizer solves exactly this problem. Seven hand-curated performance and security fixes, each with auto-safety-check (automatically detects conflicting plugins and does NOT intervene), each one-click-activatable and just as one-click reversible.
The 7 Fixes
1. Throttle the Heartbeat API
Reduces the WordPress Heartbeat frequency contextually: 60s in the admin, 120s in the post editor (instead of 15s), practically off on the frontend. php load → lower CPU throttling at your host, significantly lower TTFB value.
2. Disable XML-RPC & Pingbacks
Closes the XML-RPC endpoint (by far the most common brute-force attack target on WordPress) and disables outbound pingbacks. Auto-safety-check: if Jetpack, Wordfence, or Sucuri are active, the fix does NOT intervene — you don’t have to choose between security plugin and xmlrpc hardening. Plus REST API user enumeration protection for anonymous requests.
3. Remove Emojis & oEmbed Discovery
js, ~14 KB) and the oEmbed auto-discovery routes. Saves 2–3 HTTP requests per page load. URL embeds in the editor remain functional — only public discovery is turned off.
4. Strip Query Strings from Static Assets
ver=… from CSS/JS asset paths. Proxy and CDN caches (Cloudflare, host caches) can now cleanly cache the assets. Auto-safety-check: with WP Rocket / W3 Total Cache / WP Super Cache, the fix does NOT intervene — caching plugins handle this themselves.
5. Remove jQuery Migrate from Frontend
js (~11 KB) from the frontend but keeps it active in the admin. On modern themes (2020+), Migrate is unnecessary. Lighthouse Performance score typically increases by 1–3 points.
6. Block Author Archives (User Enumeration Protection)
author=N or /author/<name>/. Auto-safety-check: if Yoast already has Author Archives disabled, the fix does not intervene. The most well-known brute-force prep trick is neutralized — calls are 301-redirected to the homepage.
Additionally: REST API user-individual endpoints blocked for anonymous calls.
7. Hide WordPress Version from Frontend
ver= strings. External scanners and brute-force bots can no longer directly identify the exact WordPress version — version-specific exploit-sweep attacks become more expensive. Auto-safety-check: if Wordfence / Sucuri / All-in-One Security / Perfmatters are active, the fix does not intervene (they handle this themselves).
How It Works Technically
php. WordPress automatically loads must-use plugins before all regular plugins — no activation workflow needed, no reload trick, the fix takes effect immediately.
When you deactivate, the file is deleted. Standard WordPress behavior returns immediately. When you uninstall the plugin itself, ALL fix files are automatically removed.
php. php, or existing plugins. Each fix is isolated in its own file — you can inspect them yourself, and you can just as easily delete them manually if you don’t want to use the plugin anymore.
) — no direct PHP filesystem calls.
What It Does NOT Do
- Writes nothing to your database (a single wp_options entry with the list of active fixes is the exception — ~50 bytes).
- Modifies no theme files, no functions.php, no wp-config.php.
- Does not automatically deactivate existing plugins — auto-safety-check detects conflicts and skips the fix.
- Sends no user data to external servers. Fully offline-capable.
- Shows no ad banners, no nag screen, no trial expiration.

Want a free diagnosis before fixing?
com/plugin/optimizer. It runs from outside (no FTP, no login, no admin access required) and tells you exactly which performance leaks are draining your hosting plan:
- Heartbeat API hammering your CPU? Yes/No, with the live frequency.
- XML-RPC open to brute force? Yes/No, with the current attack surface.
- Author archives leaking usernames? Yes/No, with the exposed names.
- jQuery Migrate still loading in your frontend? Yes/No, with the wasted KB.
