switch-language is not activating the language after a fresh WordPress install

[robsonpessoa]

I noticed that wp site switch-language is not working after a fresh installation of WordPress 6.6.1. Even though the command prints that activated the language successfully, the en_US keeps activated as the output of the wp language core list.

I've tried the following:

$ wp language core list --status=active --format=csv --fields=language
language
en_US

$ wp language core list --status=installed --format=csv --fields=language
language
pt_BR
uk

$ wp site switch-language uk
Success: Language activated.

$ wp language core list --status=active --format=csv --fields=language
language
en_US

If I run the command with the pt_BR, the behaviour is the same, so it may not be related with the chosen language, I guess.

I also noticed that, after I change manually the language in the Settings at wp-admin to any other installed language (not the en_US) one first time, the admin pages then change its language correctly if I run the command wp site switch-language again. But the command wp language core list keeps printing en_US as the active language.

EDIT
The theme I'm using does not implement internationalization, so if I run the command wp language theme list only the en_US is listed. I'm not sure if it's related to the problem, but as I would like to change the WordPress core language, I think it shouldn't be.

May be related to #84

May be related to #84

I doubt it, because that one is specifically for en_US.

Sounds strange that the command isn't working for you. All it does is update_option( 'WPLANG', 'uk' );. So if that fails, there's probably some issue specific to your site.

BTW, just realized the site switch-language command isn't documented in this repo, nor do we have a label for it or anything.
