Hi. I don’t know how to delete a default security profile or change the default value to other profile. Is it done only through a terminal somehow? My user profile has full rights.

Hello,
You can’t delete it, but you should be able to change it.
Can you validate that you do have full right and that somehow, the “full” group wasn’t changed.
I’ve seen this before on routers that were hacked where “full” had less rights than before and a new group had all rights.
