Minecraft you open a container silent message?

I just went to my and my friends' server as normal and whenever I open a chest it says: "You are opening a container silently".

How do you go about that?

You have to turn off subtitles in the settings, I think it says

Maybe to make the chest? If it doesn't go away, it's a programming bug in a plugin

Ahh thanks, it was the plugin "openinv" and apparently I used the command / silentcontainer.

Your friends need to add you to the chest.

This message comes when you actually do not have access to the chest, but you can still open it thanks to your admin rights.

No, it was due to a plugin called openinv and there's a command with which you can set that.

Ahh true, that's it.

Had the problem once, but it was several years ago, so I didn't know exactly anymore, sorry ^^
