I dont use a Permissions.yml or any plugin which used permission groups.
I used only Op list and whitelist.
Please help me

 

NameTagEdit is not 1.10 yet. You'll just have to wait for it to be updated.

Directly from the Spigot page:

"Additionally, the reflection in use will keep the plugin compatible with several Minecraft versions (currently compatible with 1.5.2 - 1.9.x)."
