Error after Garry's Mod Update

[xLiaMz]

I updated the server since no-one could connect as it was outdated and now I get this weird bug after the Something is creating script errors panel displays. This is the error:

[ERROR] lua/includes/modules/gamemode.lua:86: attempt to index upvalue 'hook' (a nil value)
1. Call - lua/includes/modules/gamemode.lua:86
2. GetDefaultSkin - lua/derma/derma.lua:177
3. GetSkin - lua/includes/extensions/client/panel.lua:354
4. GetSkin - lua/includes/extensions/client/panel.lua:349
5. SkinHook - lua/derma/derma.lua:199
6. unknown - lua/vgui/dframe.lua:209

It stops people being able to do anything HUD related, such as F4 (DarkRP)

[B]EDIT/FIX:[/B] Just posting it here just incase anyone else needs help with this.

This is probably due to an anti cheat addon, I used Cake Anti Cheat - Update or remove it, should fix the problem.

Hope this helps :)

It is caused by one of your addons, figure out which one it is and report it if you want.

Any Lua anti cheat for that matter.
