Flip, reproduce, read, fix

1

Flip the toggle

Debug mode rewrites the flags for that one sandbox. Nothing to edit by hand.

2

Reproduce the bug

Click through the broken flow on the live site while the log records everything.

3

Read debug.log

The viewer sits right next to the toggles notices, warnings, fatals, stack traces.

4

Fix and flip back

Deploy the fix, confirm the log is clean, turn debug off. Or just reset the site.

Every WP_DEBUG constant, safely per-site

WP_DEBUG

The master switch

Turns on WordPress’s debug machinery for the sandbox the thing you never dare enable on production.

WP_DEBUG_LOG

Everything lands in one file

Notices, deprecations, fatals captured to debug.log and readable in the dashboard or over SSH.

WP_DEBUG_DISPLAY · SCRIPT_DEBUG

The supporting cast

Show errors on-page when that’s faster, and switch to unminified core scripts when chasing JS.

Chase version-specific bugs by switching PHP

A deprecation that only fires on 8.3? Switch the sandbox’s PHP version, reproduce, and read the notice in the log same site, same data.

  • ✓ PHP 8.1 / 8.2 / 8.3 per sandbox
  • ✓ Switch without rebuilding the site
  • ✓ Pair with WordPress betas for the full matrix

php version

8.18.28.3 · active

[09:20:11] switched php 8.1 → 8.3

Deprecated: dynamic property in MyPlugin\Cache

…there it is.

What debuggers ask

Do the toggles survive a reset?

Reset returns the sandbox to a clean slate; flip debug back on with one click when you need it again.

Can I read the log without the dashboard?

Yes use sandywp ssh <name> and tail -f wp-content/debug.log, or mount the files locally and open it in your editor.

Can agents use debug mode?

Yes. Toggling debug and reading debug.log are exposed over MCP and the CLI, so an assistant can close the write → deploy → debug loop alone.

Why not just edit wp-config.php?

You can it’s your sandbox. The toggle is simply faster and reversible without remembering what you changed.

Stop guessing. Read the log.
