No language change possible with Language Extension Bundle

[ManuelHaas]

Describe the Bug

Using current citizen skin (2.40), there is no possibility to switch language for a wiki that provides mulitple languages via translate extension. You can neither change the interface language nor the language of the displayed content. Functionality is working fine with timeless skin.

1. Is language support only provided if using InterWiki extension because this is not installed?
2. Or is there any config setting necessary to get a language selector button like in the german citizen wiki?

Expected Behavior

Language selection button to switch between the provided wiki languages.

System

• MediaWiki version v1.39.1
• Server OS: Ubuntu 22.04.1
• Installed extensions and versions: Language Extension Bundle 2023-01-24 MLEB 2023.01
• PHP version 8.0.27

Will look into it

So to answer your question, the language selection button only appears for any extension that modifies the languages sidebar menu by default, that includes Extension:Interwiki.

To apply this behavior for Extension:Translate, you need to put the following config in localsettings.php

$wgPageTranslationLanguageList = 'sidebar-only';

On a side note, Extension:Interwiki and Extension:Translate treat languages differently. Extension:Interwiki links independent wikis for languages (e.g. English Wikipedia and German Wikipedia are separate wikis, linked through Interwiki). While Extension:Translate links pages on the same wiki (e.g. Article/en for English and Article/de for German on the same wiki).

There is some current bugs with ULS and Translate that I am trying to fix, but I don't have an ETA at the moment because they are complicated.

Thank you very much for the detailed explanation!
So far it works well with this setting set.
