Firstly , people see me with vanish on,but sometimes they dont so i would say it bugs.Aslo it says you cant toggle that on whatever i put even if im op.Tried with the perms but still nothing.[HELP]

You need to add the perm nodes, OP doesn't give much.

As for visibility try testing with no other plugins on the server

Well added the permissions as i said but it wont work.And i think op gives u all permissions or i'm just a noob.

Owner:
prefix: '&6[&bOwner&6]&1 '
permissions:
- modifyworld.*
- permissions.*
- essentials.warp
- essentials.warps.wild
- essentials.warps.parkour1
- essentials.warp.list
- essentials.spawn
- essentials.helpop.receive
- essentials.help
- vanish.toggle*
- vanish.vanish
- usb.island*
- usb.party*
- usb.island.create
- usb.island.create
- usb.island.sethome
- usb.island.info

without the * on the toggle

This plugin (like many plugins) has its permissions specifically defined to NOT be granted to ops, for most nodes.

Try adding these nodes: vanish.standard and vanish.toggle.all
