wp_load_translations_early()

In this article

This function’s access is marked private. This means it is not intended for use by plugin or theme developers, only in other core functions. It is listed here for completeness.

Attempts an early load of translations.

Description

Used for errors encountered during the initial loading process, before the locale has been properly detected and loaded.

Designed for unusual load sequences (like setup-config.php) or for when the script will then terminate with an error, otherwise there is a risk that a file can be double-included.
