Find & Remove Unused LearnDash Content vs Sitevorx

Find & Remove Unused LearnDash Content scans your LearnDash LMS installation and identifies quizzes, lessons, and topics that are not attached to any course structure. Over time these orphaned items accumulate and bloat your database. This plugin is a third-party utility and is not affiliated with or endorsed by LearnDash or its parent company. Key Features Three-tab dashboard — separate views for Quizzes, Lessons, and Topics Smart detection — uses multiple LearnDash API methods to reliably determine usage Course column — shows the parent course even when the quiz is attached via a lesson or topic Search — filter by title, post ID, or associated course/lesson name Usage filter — switch between All / Used / Unused instantly Pagination — configurable rows per page (10 / 25 / 50 / 100) Bulk actions — Move to Trash or Permanently Delete selected items Trash All Unused — one-click button to move all orphaned items to trash CSV Export — export current filtered view to a spreadsheet Refresh Scan — clear the cache and force a fresh scan Results cached — 5-minute transient cache keeps the UI fast No external dependencies — pure WordPress APIs only Requirements WordPress 5.8 or higher PHP 7.4 or higher LearnDash LMS (tested with LearnDash 4.x) Usage Detection Logic A quiz is marked Used if it appears in at least one of: learndash_get_course_quiz_list() for any course learndash_get_lesson_quiz_list() for any lesson learndash_get_topic_quiz_list() for any topic _sfwd-quiz post meta (edit-screen association fallback) A lesson is marked Used if it has a course pointer via: learndash_get_course_lessons_list() for any course _sfwd-lessons post meta (sfwd-lessons_course field) ld_get_setting( $id, 'course' ) fallback A topic is marked Used if it has a lesson or course pointer via: learndash_get_lesson_topics_list() for any lesson _sfwd-topic post meta (sfwd-topic_lesson / sfwd-topic_course fields) Safety All destructive actions require nonce verification Only users with the manage_options capability can use this plugin Deleted items go to Trash by default so they can be restored Results are cached — click Refresh Scan before any cleanup to ensure accuracy

Sitevorx is a lightweight, all-in-one WordPress plugin that helps you optimize performance, harden security, and manage your website from a single, modern dashboard. No bloat, no external dependencies — just the tools you need. Security Center (NEW in 1.1.0) Security Score Dashboard: A single 0–100 score that summarizes the hardening state of your site, with prioritized recommendations. Core Integrity Checker: Compares every WordPress core file against the official api.wordpress.org MD5 checksums to detect modified, missing, or extra files. HTTP Security Headers: One-click enable X-Content-Type-Options, X-Frame-Options, Referrer-Policy, and Permissions-Policy on the frontend. Login Honeypot: Invisible bait field on wp-login.php that silently rejects spam bots without affecting real users. User Enumeration Protection: Blocks ?author=N probing and the public REST /wp/v2/users endpoint for non-logged-in visitors. Login Notification: Emails the administrator whenever an account with manage_options logs in successfully (1-hour cooldown per IP). Login Attempt Limiter: Lock out IPs after repeated failed login attempts, with configurable threshold, lockout duration, and IP allowlist. Secret Login URL: Hide the default wp-login.php behind a custom keyword. Google reCAPTCHA v2 / v3: Protect the login form from bots, with a configurable v3 score threshold. Disable XML-RPC and Disable File Editor: Block DDoS / brute-force vectors and stop code editing from the dashboard. Speed Optimization Heartbeat Throttle: Slows the Heartbeat API to 60 seconds instead of disabling it, preserving autosave and post-locking. System Tweaks: Lazy load images, limit post revisions, allow safe SVG uploads (with XXE-hardened sanitizer). Database Cleanup: Remove revisions, spam comments, and expired transients in one click. Malware Scanner: Scan your entire codebase and database for suspicious injections. SMTP Configuration Send emails via Gmail (App Password) or a custom SMTP server (SSL/TLS). Built-in Test Email sender. Email delivery log with success/failure tracking. Force From Name and From Email to prevent address drift. Website Utilities Inject tracking codes in Header/Footer (Google Analytics, Facebook Pixel, etc.). Content Protection: Disable right-click, text selection, and drag-and-drop. Maintenance Mode: Display a professional “under construction” page to visitors. Custom Login Logo: Replace the WordPress logo on the login screen with your own brand. Disk Space Manager Recursively scan your hosting for large files (>50 MB). Auto-categorize files (backups, error logs, large media). Bulk delete to free up disk space instantly. Floating Contact Buttons Phone Hotline button with animated icon. Zalo chat button (auto-opens Zalo app). Messenger chat button (m.me deep link). Fully responsive floating widget in the corner of your site. Import / Export Settings Export all Sitevorx settings as a JSON file. Import settings from another site in one click. Reset all settings to factory defaults. Scheduled Cleanup (WP-Cron) Automatic cleanup: daily, twice daily, or weekly. Clears temp files, auto-drafts, spam, and optimizes database tables. Activity log showing the last 20 cleanup runs. Maintenance & Update Monitor Track plugins and themes that need updating. Check WordPress core, PHP version, SSL status, and WP_DEBUG. Maintenance health score with actionable recommendations. Server Info View Web Server, PHP, MySQL, and WordPress versions at a glance. PHP limits: memory, execution time, input vars, upload size. List all loaded PHP extensions. Database size monitoring. External Services Google reCAPTCHA (v2 and v3) Sitevorx can optionally integrate with Google reCAPTCHA (v2 checkbox or v3 invisible / score-based) to protect the WordPress login form. This feature is disabled by default and only works when an administrator explicitly enables it, selects a version, and provides valid Google-issued API keys. When enabled, the plugin loads the Google reCAPTCHA JavaScript on the login screen and sends the generated verification token to Google’s verification endpoint (https://www.google.com/recaptcha/api/siteverify) during login validation. For v3, the configurable score threshold (filter sitevorx_recaptcha_v3_score_threshold, default 0.5) is compared against Google’s returned score.
