ListingCore Diagnostics

ListingCore Diagnostics inspects a WordPress installation and reports what it can directly observe — versions, update state, security and performance configuration, database metadata, error-log activity, and more — without guessing.

Project Philosophy:

ListingCore Diagnostics should report what it can prove, not what it merely suspects.

Current capabilities:

• 32 static, read-only, deterministic diagnostics across core, configuration, security, performance, database, plugins, and themes.
• A factual diagnostic summary (total, severity, and category counts) with no scoring or interpretation.
• Aggregate evidence only — no raw option dumps, credentials, or paths.
• One reversible fix (fix.site_urls_align) with preview, confirmation, verification, and rollback.
• A capability-gated admin page with fully escaped output.

ListingCore Diagnostics deliberately avoids speculative diagnosis, plugin blame, root-cause claims, health scoring, AI/ML, arbitrary filesystem scanning, arbitrary SQL, external HTTP, and telemetry. Diagnostics are read-only; the only mutation path is a single, explicitly confirmed, nonce-protected fix.

Requirements

• WordPress 6.0 or higher
• PHP 7.4 or higher
• MySQL 5.7 or higher (or MariaDB 10.2+)

Security

• Diagnostics are read-only and aggregate-only
• The single fix requires the manage_options capability and a valid nonce
• All output is escaped
• No external HTTP, telemetry, or automatic data modification
