Key points

What you see in the admin

Visitors see nothing. The check screen shows each plugin and theme with a verdict, and a finding leads to the file and line.

What the admin gets

Health checks give a specific fix and a link. In Pro the conflict test switches plugins off only in your browser for 2 hours, and the real plugin list does not change.

How much it costs

The base version is free. Pro costs 990 UAH for a one-year licence. A year of updates, technical support and all Pro features.

The trial starts when you ask

A fresh install is the free version, nothing switches on by itself. The “Try Pro for 7 days” button → e-mail → the key right in the window and by e-mail.

One key — a site and a staging copy

Moving the site? Unlink the licence on the old domain and activate it on the new one yourself. A staging copy (staging., dev.) works with the same key and does not take a site slot. For studios — keys for 5 or 25 sites, or unlimited.

Technical requirements

  • WordPress 6.2+, PHP 7.4+.

Full module description

Site Doctor shows what will break on a new PHP version before you update, and what is wrong with the site now. It runs on any WordPress.

What you see in the admin

Visitors see nothing. The check screen shows each plugin and theme with a verdict, and a finding leads to the file and line.

What the admin gets

Health checks give a specific fix and a link. In Pro the conflict test switches plugins off only in your browser for 2 hours, and the real plugin list does not change.

How it works, step by step

  1. You pick the target PHP version.
  2. The plugin reads the code of plugins and themes.
  3. It shows a verdict and findings.
  4. Health checks show the other problems.
  5. In Pro the log catches errors after updates.

Under the hood

  • The analysis is static: code is not run.
  • The conflict test writes an mu file for the time of the test.
  • WP-CLI commands are included.

How to install

  1. Plugins → Add New → Upload Plugin: pick the zip and activate.
  2. Open Site Doctor in the admin and run the check.
  3. For Pro: paste the key or start the 7-day trial.

The module is not on wordpress.org yet: the free version and Pro are one archive from this page. Without a key it works as the free version.

@catcode_support Setup, compatibility, activation
Is this a promise of compatibility?

No, it is static analysis. Test a copy of the site before a PHP update.

Is WooCommerce needed?

No.

Do visitors see the conflict test?

No, it works only in the admin browser.
