Rocket Launcher no more Work all other weapons work.

Any Help?

The console output you are showing is expected.

Secondly do not use a permission-granting plugin to manage the oxide permissions they don't work/are bugged.
( For example, the free one from code-fling is broken don't use it )

It would be best if you did it manually in the console using oxides commands.
