CB Site Health & Debug is a two-part tool for developers and site owners who want to know why a page is slow and what to fix, without digging through server logs.

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.
