CB Site Health & Debug

1. Front-end debug bar

A toolbar item (visible only to logged-in administrators) that opens a panel showing, for the exact page you’re looking at:

• Database queries, with timing and the code that triggered each one (requires SAVEQUERIES)
• Hooks and actions fired, with counts
• _doing_it_wrong() calls and deprecated function/argument/hook usage
• PHP notices, warnings, and errors
• Outbound HTTP API calls and their response times
• Enqueued scripts and styles, with handles, sources, versions, and dependencies
• Loaded text domains, transient writes, and capability checks
• WordPress lifecycle timing (plugins_loaded → init → template_redirect → footer)
• Template hierarchy and conditional tags
• A custom cbdd_log( $value ) helper you can call from your own code to send values to the panel, the same way you’d use error_log()

2. Site Health & Debug report (Tools menu)

A page that scans your site for common performance and configuration problems and rates each one Good / Warning / Needs Fixing, with a plain-English explanation and a fix — covering PHP/server settings, database bloat (autoloaded options, revisions, expired transients), caching (object cache, page cache), overdue cron events, unoptimized images, and — when WooCommerce is active — Action Scheduler backlogs.

It also includes:

• One-click cleanup — remove expired transients, delete old post revisions, clear the slow-query log
• Slow query log — queries over a configurable threshold are saved across visits, not just the current page load
• History & trend — a daily snapshot shows what’s newly failing or fixed since the last check, and a 10-day trend table
• Admin menu badge — a red count bubble on the Tools menu when critical issues exist, refreshed daily even if nobody opens the page
• Optional weekly email digest — a summary of critical/warning findings sent to an address you choose

Everything is restricted to users with the manage_options capability. Nothing runs for site visitors, and no data leaves your site — there is no external service, tracking, or license check involved.
