I have given the correct (negated) permission to my admins but still goin with the Invisability II effect. yes i have disabled allow-silent-join-quit: to false..

There is no allow-silent-join-quit in VanishNoPacket, nor do I recall having an enchantment applied. Are you sure you're talking about this plugin?

Sounds like an Essentials issue...

I ment the essentials config, i have disabled allow-silent-join-quit and it still joins me with Invisibility II.
And can this be fixed with this plugin?

This plugin is not Essentials, nor will it fix problems you have while still using Essentials.
