Bug with l10n cache since fixed, as far as we know.
I need variable for this [1] (in red circle). I thought that this is it (translation in croatian is here), but it seems that is not what I want to translate.
You should use SearchTranslations: it's at MediaWiki:Ext-uls-input-settings-more-languages-tooltip/hr.
I appreciate your answer. Thank you very much.
Message on hr.wiki is still in english. What's wrong?
