Problem/Bug Pressure Plates not activating when a player triggers them.

On my server, we have Launchplates to launch you to different islands. (The plugin we use is linked here.)
However, when a De-OPed player walks onto the Pressure Pad it does not activate. (When an OPed player walks onto the Pressure Pad it activates.)

Then perhaps your launchplates have permissions.

 

No, they don't, I have tried with other plugins and its not the plugins error. Thanks anyway.
