If I add a language from my LocalSettings.php using:
$wgExtraLanguageNames['wy'] = 'Wayuunaiki';
Then the language is properly registered in MediaWiki (it can be selected from my preferences) but it's not searchable through the ULS (for example in the dropdown list of the Translate extension, when selecting the language I want to translate to). I tried running the script:
but still nothing. Is this normal behavior? Is it a bug? What do I need to do to make my newly registered language searchable? Thanks!!
