How to delete spamming message when i click on chest or other lockable block?
Message is written in Russian language

Look at the BlockProt/lang/translations_ru.yml file and look for lock_hint: "..." and delete the contents so its just lock_hint: "". The message will be gone then, however, it should also only appear until you open the menu at least once. So, have you done what the message says?

It's work, thanks for answer
