Hello, how to remove this login alert? => https://imgur.com/a/VaBWMKK

Pretty sure this might be an EssentialsX setting.

But when I delete NametagEdit the message disappears!

The joined likely still appears, but the tag does come from NTE likely.

We don't have any joined chat settings.

So what should I do to remove this message?

If you fill this out. I wouldn't have to guess.

Type /ver NametagEdit and post the output.

What version of Bukkit/Spigot/PaperSpigot are you using? Type /ver

What plugins are you using? Type /plugins

Please explain your issue. How do you trigger it?

Are there any errors in the console? Please use: https://pastebin.com
