[411] Fix | Delete

* Filters whether to allow the debug mode check to occur.

[412] Fix | Delete

*

[413] Fix | Delete

* This filter runs before it can be used by plugins. It is designed for

[414] Fix | Delete

* non-web run-times. Returning false causes the `WP_DEBUG` and related

[415] Fix | Delete

* constants to not be checked and the default PHP values for errors

[416] Fix | Delete

* will be used unless you take care to update them yourself.

[417] Fix | Delete

*

[418] Fix | Delete

* To use this filter you must define a `$wp_filter` global before

[419] Fix | Delete

* WordPress loads, usually in `wp-config.php`.
