If I enable language for UI for some journal (Polish for https://lmaleidykla.lt/ojs3/index.php/menotyra), the language is enabled for main page too (https://lmaleidykla.lt/ojs3/). Is it possible to enable language UI for one journal only, not for the whole site?
Unfortuantely not. The main site has allways enabled all the languages. You can select lanugages per journal, but not for the main site.
Where in the source should I look in order to disable some language for the main page?
