Changeset 37855 for trunk/src/wp-includes/l10n.php

Timestamp:

Message:

I18N: Enable unloading of text domains that have been loaded just in time.

[37415] removed the requirement to call load_plugin_textdomain() / load_theme_textdomain(). This caused unload_textdomain() to not work properly anymore in these cases.

With this change, unloaded text domains need to be explicitly loaded manually if you want to use them again.

Props swissspidy, ocean90.
Fixes #37113. See #34114.
