FAdmin Problem

Hello,

I’ve created a darkrp server with some addons yesterday.

Well, I’ve set myself to superadmin at ulx but if i try to set myself superadmin with fadmin, it says, the group doesnt exist.
If I click edit groups it only shows me the group user and an lua error.
ERROR:
[ERROR] gamemodes/darkrp/gamemode/modules/fadmin/fadmin/access/cl_init.lua:260: attempt to index field ‘user’ (a nil value)

  1. DoClick - gamemodes/darkrp/gamemode/modules/fadmin/fadmin/access/cl_init.lua:260
  2. unknown - gamemodes/darkrp/gamemode/modules/fadmin/fadmin/cl_interface/cl_controls.lua:301

FAdmin gives me an error everytime i try to do something permission-related on fadmin.
