Hi, I have translated select2.js file by my previous thread: https://toolset.com/forums/topic/translation-in-parent-selector/
But now I looked into the form hidden link and the field Autor is again in English (Please enter 2 or more characters,..) . I am not sure what´s wrong, because the translated file is still there.
Indeed I see the correct setup has been made so I suspect that there might be some caching involved. If there are any cache on your website or server I clearing the cache because it could be loading a previous version of the file.
It was probably caused by some cache... I tried almost everything.. I even found the same file in other Toolset plugins, so I placed the translated version there.. I tried to view the site on other devices.. But now after many days, voilà it displays correct language.
