Hungarian: Magyar nyelvű bővítmény leírás RefiTune – Site refiner toolkit is a modular Swiss Army knife for WordPress. Clean up unnecessary front-end code, harden login and uploads, tune Heartbeat and updates, or brand wp-login – each module is opt-in. Enable or disable features individually. A clean dashboard shows what is active. In-plugin Help pages document behaviour, trade-offs, and requirements. What’s Inside? (35 Modules) Performance: * Header Cleanup – Strip unnecessary wp_head output for leaner pages. * Feed Management – Control RSS/Atom feed link tags in the document head. * Disable Emoji – Remove WordPress emoji scripts and styles. * Disable jQuery Migrate – Drop legacy jquery-migrate when your stack does not need it. * Disable oEmbed – Stop automatic embeds from pasted YouTube, Vimeo, Twitter/X, and similar URLs. * Remove Asset Version Query Strings – Strip ?ver= from front-end CSS/JS (can break cache busting; prefer CDN purge or hashed filenames). * Post Revisions Limit – Cap stored revisions per post. * Auto-save Interval – Change how often the editor auto-saves. * Trash Auto-Delete – Set trash retention; expired items are removed in batches so large queues stay memory-safe. * Convert Uploads to WebP – Convert JPEG/PNG to WebP on upload, optional max size resize, then remove the original (GD or Imagick with WebP; uses unique filenames and refuses unsafe overwrites). * Heartbeat API Control – Tune or disable Heartbeat in admin, front end, and the post editor. Security: * Hide Generator Tags – Remove WordPress (and WooCommerce, when active) version meta tags. * Disable XML-RPC – Respond to XML-RPC with 404 and remove RSD discovery. * Disable Trackback/Pingback – Close pings and strip pingback methods/headers. * Disable File Editor – Set DISALLOW_FILE_EDIT so theme/plugin editors stay off. * Automatic Updates Control – Tri-state plugin, theme, translation, and core updates; reschedule update checks. Respects AUTOMATIC_UPDATER_DISABLED and WP_AUTO_UPDATE_CORE when defined. * Login Error Messages – Generic login errors to reduce username enumeration. * Restrict Admin Access – Choose which roles may open wp-admin UI. Users with manage_options always keep access. Front-end admin-ajax.php is intentionally not blocked. * REST API Restrictions – Limit selected core REST routes to users with manage_options. * Login Limit – Rate-limit failed logins by IP and IP+username pair (REMOTE_ADDR only). Optional IP whitelist (one address per line). Covers wp-login.php and other wp_signon() paths (including WooCommerce). * Verified Upload – Block disguised uploads: double extensions, MIME/magic mismatches, and script markers. Visual: * Hide Admin Bar – Hide the admin bar for selected roles. * Block Visibility (Mobile) – Show/hide blocks by device via wp_is_mobile(); sends Vary: User-Agent (full-page caches must honour it). * Login Page Customization – Brand wp-login.php with logo and colours. Email: * Email Notifications – Disable or redirect selected WordPress system emails. * Email sending – SMTP with encrypted password storage, or disable all site emails. In production, disabling TLS/certificate verification is blocked. Miscellaneous: * Disable Comments – Site-wide comments off (optional WooCommerce review keep). * External Links in New Window – Open external links in a new tab with safe rel attributes. * Enable Page Excerpt – Excerpt support for pages. * Clean Upload Filenames – Sanitize upload filenames (accents, spaces, special characters). * SVG Upload – Role-gated SVG uploads with allowlist-based sanitization (XXE-safe parse). * AVIF Upload – Role-gated AVIF uploads (full core AVIF support needs WordPress 6.5+). * Role Redirects – Per-role login and logout redirect URLs. * Maintenance Mode – 503 maintenance page for guests; chosen roles keep access. Admin, AJAX, and cron stay available so staff can work. * Dynamic Year Shortcodes – [refi-year] and [refi-year from="2006"].
