Configuration Constants

The following PHP constants can be defined in your wp-config.php file in order to control the behaviour of Query Monitor:

QM_DARK_MODE

Enable dark mode for Query Monitor’s interface.

Default false

QM_DB_EXPENSIVE

If an individual database query takes longer than this time to execute, it’s considered “slow” and triggers a warning.

Default 0.05

QM_DISABLED

Disable Query Monitor entirely.

Default false

QM_DISABLE_ERROR_HANDLER

Disable the handling of PHP errors.

Default false

QM_ENABLE_CAPS_PANEL

Enable the Capability Checks panel.

Default false

QM_HIDE_CORE_ACTIONS

Hide WordPress core on the Hooks & Actions panel.

Default false

QM_HIDE_SELF

Hide Query Monitor itself from various panels. Set to false if you want to see how Query Monitor hooks into WordPress.

Default true

QM_NO_JQUERY

Don’t specify jQuery as a dependency of Query Monitor. If jQuery isn’t enqueued then Query Monitor will still operate, but with some reduced functionality.

Default false

QM_SHOW_ALL_HOOKS

In the Hooks & Actions panel, show every hook that has an action or filter attached (instead of every action hook that fired during the request).

Default false

QM_DB_SYMLINK

Allow the wp-content/db.php file symlink to be put into place during activation. Set to false to prevent the symlink creation.

Default true
