Enable UI language for one journal only

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?

Hi @Nerijus_Baliunas,

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?
