Bug Report

Type /ver NametagEdit and post the output.
4.4.10

What version of Bukkit/Spigot/PaperSpigot are you using? Type /ver
git-Spigot-db6de12-18fbb24 (MC: 1.8.8)

What plugins are you using? Type /plugins
nte, essentials, animated tab

Please explain your issue. How do you trigger it?
I can't see the prefix on my head

Are there any warning in the console? Please use: https://pastebin.com
As the error above suggests, you do NOT have any placeholder plugins installed. The placeholder API is merely an interface, it requires other plugins to function. This is NOT an issue with NametagEdit.

Thanks for reading

How this says, its not a NameTagEdit issue "This is NOT an issue with NametagEdit.", btw try removing animated tab and see if it works
