Hello,
So my essentials plugin is blocking any plugin where it gives me and my players prefixes, for example, I tried Power ranks and much more and made my prefix [Owner] and it won't show but as soon as I disable essentials its works I really need prefixes but also need essentials.....PLEASE HELP

you need to use vault

I don't get what your saying

Install Vault - Essentials prefixes won't work without it.

You can download Vault from here.
