wp_load_translations_early does not without WPLANG defined

[szepe.viktor]

In the Hungarian WP 4.0 the maintenance text appears in english.

This is once WordPress is installed, yes?

And installed with the English package but then choosing Hungarian during install, rather than using the Hungarian package.

[szepe.viktor]

Yes, the Hungarian packages has $wp_local_package = 'hu_HU';

This is a problem with all the language packages not just Hungarian.

I may have found the solution, see:

You need to make sure $wp_local_package = 'YOUR LOCAL'; is defined at the end of wp-includes/version.php

The error may come from an upgrade, I had the same issue, and I could fix it this way.

This global variable is defined when you download a localized package from a local site like hu.wordpress.org.

Sadly, there is nothing we can do. We can't access the locale option because wp_maintenance() is loaded before a database connection can be initialized. wp_load_translations_early() is also used for database errors so we can't access the database here too.

Closing as a wontfix, but feel free to reopen if you have a patch ready.

Maybe $_SERVER['HTTP_ACCEPT_LANGUAGE'] could be an alternative source for setting the locale.

HTTP_ACCEPT_LANGUAGE

[soulseekah]

Attached a simple HTTP_ACCEPT_LANGUAGE-based locale detection.

Regular expression based on a locale list from here ​https://stackoverflow.com/questions/3191664/list-of-all-locales-and-their-short-codes#3191729

This is in no way a substitute for the deprecated WPLANG constant. We need to find a way to set the language for those notices without using WPLANG now.
