Site Diagnostics

Inspect plugin-level issues, surface conflicts, run Safe Mode and analyze logs, built for admins who want clear actions, not noise, when WordPress starts misbehaving.


What it does

Built for one job, done well.

🔍
Conflict detection
Identifies which plugin or theme is causing slowdowns, errors or instability — using a binary-search approach that narrows it down fast without deactivating everything manually.
🛟
Safe Mode integration
Puts the site into a controlled diagnostic state for your session only — visitors see the normal site while you isolate the problem in wp-admin.
📋
Log analysis
Reads the WordPress debug log and surfaces the most recent errors in a clean, timestamped view — no FTP or file manager needed to read what went wrong.
📧
Scheduled health emails
Weekly or monthly health reports sent to the admin inbox — health score, conflict signals, log size and cron status — so you stay informed without checking manually.
🔐
Security signals
Spots risky configurations — exposed debug mode, file editing enabled, outdated PHP — and surfaces them as actionable flags, not a vague score.
🎯
Health score
A single readable score across plugin health, server config, log activity and cron status so you can tell at a glance if anything needs attention.

FAQ

Questions admins actually ask.

What does conflict detection actually find?
It identifies which specific plugin or theme is causing errors, slowdowns or instability by running a controlled diagnostic scan from inside wp-admin. You get a clear list of suspects ranked by impact — not a generic "deactivate your plugins" suggestion.
Does it require WordPress debug mode to be turned on?
No. Site Diagnostics works without WP_DEBUG enabled. However, if debug logging is active, the plugin will also read and surface entries from your debug.log file in a clean, readable timeline.
What are scheduled health emails?
A weekly or monthly summary sent to the WordPress admin email address — covering your health score, any new conflict signals, log file size, and cron job status. You stay informed without logging into wp-admin to check.
Will running diagnostics affect my visitors?
No. All diagnostic checks run server-side in the background. The Safe Mode feature applies only to your own admin session — visitors continue to see the normal live site throughout.
Does Site Diagnostics send any data externally?
No. All health checks, log analysis and conflict detection run entirely on your own server. No data is sent to any external service, analytics platform or third party.
