It does not claim that correlation proves causation. All features are included for free. #### Included features * Activity timeline for important WordPress changes. * Plugin activation and deactivation logging. * Plugin, theme and WordPress update logging. * Environment snapshot comparison to detect version and activation changes. * Theme switch logging. * Content creation, editing and deletion logging. * Important WordPress settings change logging. * User account and role change logging. * Successful and failed login logging. * PHP fatal error capture with duplicate suppression. * wp_mail failure logging. * 404 spike detection without storing requested URLs. * Detective Scan that ranks recent events by diagnostic relevance. * Incident Center that groups related events into a readable diagnostic timeline. * Site Score showing recent operational risk at a glance. * Manual and optional automatic read-only site tests with history and degradation- only alerts. * Homepage and REST API response checks. * HTTPS, PHP, WP-Cron and debug-display checks. * Critical event e-mail alerts with rate limiting. * CSV and JSON export. * Configurable log retention. * IP privacy mode: IP addresses are hashed by default. * WordPress personal-data exporter and eraser integration. * Responsive WordPress admin interface. * Error Trends with 7/14/30-day visual history. * Plugin Health diagnostic profiles for active plugins. * Standalone incident detail with forensic timeline. * Database table change detection between diagnostic snapshots. * Automatic problem lifecycle: new, recurring, current and historical diagnostic signals. * Recency-weighted Site Score so old non-recurring errors have less impact on the current state. * No telemetry, no external WebCrew account, no license key, no paid feature gates. #### Privacy Site Detective stores its diagnostic data in the local WordPress database. By default, client IP addresses are pseudonymized using a one-way HMAC hash. Administrators may explicitly enable full IP logging. The plugin does not send diagnostic data to WebCrew or another external service. The Diagnostics page performs requests to the site’s own homepage and REST API when opened by an administrator. ## Installation 1. Upload the plugin folder to `/wp-content/plugins/` or install the ZIP in Plugins > Add New > Upload Plugin. 2. Activate WebCrew Site Detective. 3. Open Site Detective in the WordPress admin menu. 4. Review Settings and choose your preferred retention and alert options. ## FAQ ### Does Site Detective automatically repair my site? No. Its goal is to collect evidence and make troubleshooting faster without making risky automatic changes. ### Does Detective Scan identify the exact cause? It ranks recent events by diagnostic relevance. A high score means an event deserves investigation; it is not proof that the event caused the problem. ### Does the plugin send data to WebCrew? No. There is no telemetry or WebCrew account connection. ### Is there a Pro version? No. All functionality shipped in this plugin is free. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “WebCrew Site Detective” is open source software.

Changelog #### 3.4.0 * English is now the default Site Detective admin language. * Czech remains available as an optional admin language. * Added Czech translation files: cs_CZ PO/MO and a POT template. #### 3.3.0 * Added Change Radar on the dashboard to compare the latest technical test with the last healthy baseline and show diagnostic activity since then. * Added a performance noise guard so Site Detective does not report its own admin screens or WordPress Heartbeat as slow requests. * Improved dashboard context with direct links to Timeline, Before / After and the site test when a baseline needs verification. * Kept all new UI bilingual in Czech and English and read-only by design. #### 3.2.1 * Removed the Plugin URI header until a dedicated public plugin page is available. * Removed the hardcoded uploads fallback and now rely only on wp_upload_dir() for upload-directory detection. * Updated free-space diagnostics to use the WordPress-resolved uploads path instead of a content-directory constant. * Re-audited privileged admin actions for capability and nonce checks. #### 3.2.0 * Added full Czech/English administration language selection with Auto, Czech and English modes. * Expanded English localization across navigation, diagnostics, settings, site tests, reports, cleanup and event messaging. * Critical alert and privacy text now follow the selected Site Detective language. * Kept the WebCrew branded text-free header and all existing diagnostics unchanged. #### 3.1.2 * Plugin Check compatibility fix for the bilingual admin output buffer. * Documented the already-escaped, plugin-generated admin markup so PHPCS does not report a false positive. #### 3.1.1 * Fixed admin header caching by moving the new text-free WebCrew artwork to a versioned asset filename and adding an explicit version query. * Removed the obsolete header filename so stale browser/CDN caches cannot silently substitute the previous artwork. #### 3.1.0 * Replaced the in-plugin admin header artwork with the new text-free WebCrew branded hero background. * Added built-in bilingual admin support for Czech and English based on the current WordPress/user locale. * Localized the main navigation, header actions, site health messaging and key admin interface labels for English users. #### 3.0.7 * Plugin Check hardening release: fixed escaping, sanitization and prepared SQL findings. * Removed the obsolete manual text-domain loader and unused Domain Path header. * Reworked custom-table queries to use identifier placeholders and documented unavoidable direct diagnostic queries. * Hardened read-only admin filters with explicit nonce-analysis annotations and sanitized array inputs. * Replaced direct CSV file-handle output with in-memory CSV generation. * Improved multisite uninstall variable prefixing and safe plugin-owned table cleanup. #### 3.0.6 * Replaced the custom WordPress admin-menu image with the native Visibility Dashicon for cleaner alignment. * Replaced the Site Detective header mark with the supplied WebCrew logo asset. * Reworked desktop navigation layout to prevent labels and items from overlapping at intermediate widths. * Centered the icon and text in the manual site-test action button. * Fixed Before / After change dots to use semantic change colors instead of the legacy purple notice color. * Rebuilt Database Detective into a compact responsive three-column card grid and shortened long lists to the most useful items. #### 3.0.5 * Reworked the desktop navigation into two structured groups: diagnostics and tools/ settings. * Added consistent icon tiles and a dedicated Site Detective WordPress admin-menu icon. * Improved the branded WebCrew header with a clearer plugin identity block and monitoring state. * Added one-click Otestovat web and Detective Scan actions directly to the header. * Kept Site Score, version and the community call-to-action visible while improving responsive behavior. #### 3.0.4 * Rebuilt the WordPress admin header around the supplied WebCrew brand artwork while keeping Site Detective status, score and version readable. * Replaced the generic WebCrew link with a prominent “Připojit se do komunity” call-to-action. * Redesigned desktop navigation into a compact WebCrew control dock with clearer active states. * Added stronger card hierarchy, spacing and responsive polish across the Site Detective administration. * Kept the new branding asset local to the plugin; no external image or tracking request is added. #### 3.0.3 * Fixed a possible fatal error in the Troubleshooter when Admin and Detector code are temporarily out of sync after an update. * Troubleshooter scoring now uses a guarded compatibility wrapper with a conservative fallback. * Added extra resilience for stale OPcache / mixed-file deployments so a diagnostic helper cannot take down wp-admin. #### 3.0.2 * Fixed false database-schema warning after patch releases by comparing against the dedicated DB schema version. * Detective Scan now groups repeated identical signals instead of showing duplicate candidate cards. * Site Score now limits repeated identical error deductions while still preserving recurrence as risk. * Plugin Health treats fatal errors that predate a newer plugin version as historical evidence with substantially lower current weight. * Redesigned Documentation with WebCrew UI, topic cards, quick navigation and instant local search. * Cached monitoring settings per request and stopped loading heavy admin/diagnostic classes on ordinary frontend requests. * Additional mobile UI polish. #### 3.0.1 * UI/UX audit for desktop and mobile administration. * Redesigned WebCrew-branded header with clearer privacy/local-data messaging. * Added compact mobile section selector instead of overflowing tab navigation. * Timeline now uses server-side pagination with 30 events per page. * Timeline filters preserve pagination context and now include a reset action. * Event counter now supports the same search/type filters as the timeline query. * Added responsive layout fixes for header, filters, cards, long text and pagination. #### 3.0.0 * Stable 3.0 release after the RC1/RC2 hardening cycle. * Finalized multisite activation, deactivation and uninstall handling. * Finalized cron self-healing and snapshot scheduling behavior. * Finalized safe exports, CSV formula-injection protection and diagnostic bundle generation. * Finalized incident feedback, retention controls and plugin-leftovers cleanup safeguards. * Removed release-candidate version identifiers and prepared the package for stable distribution. #### 3.0.0-rc2 * RC2 release hardening for multisite, admin JavaScript and retention UX. * Network activation now initializes Site Detective tables/settings/cron per existing site. * Newly created sites are initialized automatically while the plugin is network- active. * Network deactivation clears Site Detective cron hooks and locks on each site. * Snapshot cron is scheduled only while Snapshot Monitoring is enabled. * Removed inline administrative JavaScript; confirmations and bulk selection use assets/admin.js. * Cleanup screen now reflects the configured mini-backup retention instead of a hard-coded value. * Added stricter incident ID and time-range validation. #### 3.0.0-rc1 * Release candidate focused on stability and WordPress.org readiness. * Fixed recovery handler that could itself fatal when an admin diagnostic module failed. * Expanded error isolation to include header/dashboard rendering. * Added strict allowlist for admin tabs and export formats. * Added CSV formula-injection protection for exported event data. * Separated database schema version from plugin release version to avoid unnecessary dbDelta runs. * Added lightweight cron self-healing for cleanup, snapshots and optional scheduled site tests. * Snapshot cron now respects the Snapshot Monitoring setting. * Multisite snapshots include network-active plugins. * Theme, Customizer and menu logging now respect their related monitoring settings. * Closed-incident retention also removes only the matching feedback rows. * Full uninstall now removes the event-feedback table and release-candidate transients. * Additional input sanitization and release-hardening fixes. #### 2.8.0 * Added false-clue feedback for incident events. * Added event feedback database table and incident-specific relevance override. * Added safe admin rendering boundary so a diagnostic module error does not blank the whole Site Detective screen. * Improved empty/error states and mobile forensic actions. * Hardened feedback actions with capability checks, nonces and strict validation. #### 2.7.0 * Added separate retention controls for site-test history, Before/After snapshots, cleanup mini-backups and closed incidents. * Added daily pruning of auxiliary Site Detective data in addition to event-log retention. * Added an opt-in complete data removal on uninstall; diagnostic history remains preserved by default. * Added Site Detective storage usage summary in Database Detective. * Added a one-click action to apply all configured retention limits immediately. * Added a privacy-conscious diagnostic JSON bundle for support handoff. * Snapshot and test history limits are now configurable instead of hard-coded. * Cleanup mini-backup retention is now configurable. * Closed resolved/ignored incident states can be pruned after a configurable period; active investigations are preserved. * Improved release hardening for local-only data management and multisite-safe per-site storage. #### 2.6.0 * Added safe Plugin Leftovers Cleanup for data left behind after confirmed plugin deletion. * Records successful plugin deletion events for reliable ownership context. * Detects matching wp_options entries, transients, and plugin-prefixed custom tables. * Never cleans anything automatically; every item requires administrator selection. * Protects installed and merely deactivated plugins from destructive cleanup. * Database table removal requires a separate explicit confirmation. * Keeps up to five bounded local mini-backups of removed option values. * Added cleanup guidance and safety documentation. #### 2.5.1 * Fixed a fatal error in the Troubleshooting Wizard caused by a missing public event-scoring method. * Added defensive validation for malformed or incomplete event rows in wizard results. * Improved result sorting when two diagnostic clues have the same score. * Hardened date/title/description rendering so an incomplete log entry cannot break the admin screen. #### 2.5.0 * Added Site Detective Self-Test for database tables, cron jobs, snapshots and active monitors. * Added transparent Site Score breakdown explaining each deduction. * Expanded Incident Inbox with full-text search, event-type filtering and reset controls. * Added bulk incident status actions for New, Investigating, Resolved and Ignored. * Added mobile UI for self-test, score explanation and bulk incident controls. #### 2.4.0 * Added optional automatic read-only site tests via WP-Cron. * Added daily or weekly test frequency. * Added degradation-only email notifications: unchanged persistent issues do not trigger repeated alerts. * A degradation is reported when the test score drops by at least 5 points, the critical count increases, or a check newly becomes critical. * Added automatic/manual source labels to Site Test history. * Added next/last scheduled test status to the Site Test and Settings screens. * Added a local timeline event when a scheduled test detects a meaningful degradation. * Extended in-plugin documentation for scheduled tests and alert behavior. * No automatic repairs, plugin deactivation, telemetry or external service dependency were added. #### 2.3.0 * Added Site Test History with up to 20 local results. * Added technical score trend chart. * Added comparison of improved, worsened and persistent checks. * Added score delta versus the previous test. * Added history UI optimized for desktop and mobile. #### 2.2.0 * Added one-click read-only

prioritizes the last 24 hours instead of presenting older incidents as current failures. * Added recurrence detection using local error fingerprints or matching event type/ title. * Site Score now uses recency-weighted critical and warning penalties. * Older incidents have a much smaller effect on the current Site Score when they do not recur. * Plugin Health distinguishes current plugin signals from historical signals after a newer plugin change. * Added lifecycle badges to Detective Scan, Incident Center, Incident Detail and Plugin Health. * Dashboard KPIs now clearly show current 24-hour critical events, incidents and slow requests. * Added lifecycle event caching to keep the new classification lightweight in admin screens. * Historical does not mean fixed; it only means the signal is no longer recent. #### 1.8.0 * Added first-run onboarding explaining when monitoring starts and how to use Site Detective. * Added persistent Monitoring Status strip on the main dashboard. * Added detailed monitoring status panel in Settings. * Shows active detectors, e-mail alert state and scheduled snapshot state. * Added safe onboarding dismissal without disabling monitoring. *

Center. * Successful plugin/theme installs are no longer shown as warnings. * Slow requests now use a dedicated Performance label and purple marker. * Fixed mobile incident dots overlapping event titles. * Improved Plugin Health colors and Czech labels. * Historical fatal signals are de-emphasized when a newer plugin change happened afterwards. * Site Score no longer penalizes normal installs/updates merely because older log rows used warning severity. * Improved install/update titles and destination-name detection. #### 1.7.0 * New “Co se stalo?” home experience focused on plain-language diagnosis. * Added relation labels: Pravděpodobně souvisí, Možná souvisí and Informativní. * Added guided 1–2–3 troubleshooting steps for the most relevant clue. * Added latest incident summary and key clues directly to the main screen. * Added relation badges to Detective Scan and forensic incident events. * Improved mobile cards, spacing and responsive troubleshooting flow. * Kept

file locations without claiming automatic causation. * Added Incident Story with a concise narrative and the most relevant chronological steps. * Added Database Detective with database size, largest tables and custom-table overview. * Added autoload option size diagnostics without reading or exporting option contents. * Added REST Endpoint Health checks for core WordPress REST endpoints. * Added heuristic Cron source hints to make scheduled tasks easier to investigate. * Improved mobile UI for fatal error explanations, database rows and incident stories. * No automatic cleanup, deletion or remote telemetry was added. #### 1.5.1 * Fixed a fatal error in Incident Center caused by an invalid third argument passed to array_intersect(). * Improved fatal error rendering on mobile: stack
