Hello. I don't know how do this happend. I did not log into Minecraft for a month, and when I decided to log in, I went to the server. Then I wanted to write a message to the chat, but the error "Unable to send a message" appeared, although I could print commands. Well, that is, I cannot print ordinary text messages, since an error appears, but the commands can and they work. I don't know why or how this happened, but can you please help? I think this is a bug because before I could write both commands and text messages.
