No buttons work after clicking them
Ive given myself/admins the required permissions and the /padmin UI is show however when i click on anything, Kill, Dmg, Heal, Teleport etc nothing happens. Any fixs?

I would need more information pertaining to this.

Did you grant the users "clicking" the buttons, the required permissions to each command used? For example: 

Healing -> playeradministration.access.heal
