Sandbox Gamemode Errors

I just recently got a problem in Garrysmod

The following code:

ERROR: GAMEMODE:'OnSpawnMenuOpen' Failed: sandbox\gamemode\spawnmenu/spawnmenu.lua:66: attempt to call field 'SpawnMenuOpen' (a nil value) 

Appears in yellow text whenever I open my spawn menu.

I also get another similar problem when I kill something:

base\gamemode\cl_deathnotice.lua:94: attempt to call field 'IncBaddies' (a nil value)

It also appears in yellow text (doesn’t that mean a LUA error?)

This happened recently, and I can only think of two possibilities:

  1. The new update
  2. I downloaded GPK Gamemode (Garrys Mod Parkour)

I actually deleted GPK, and the problem is still there…

I own the following games that are in GMod: Portal, TF2, and CS:S

Any help is appreciated.

~Rate Agree If You Have The Same Problem!~

Clean your gMod and then reinstall your addons one-by-one, until the effect comes back again (you’ll then know which addon is breaking it)

I was hoping to avoid this :bang:

I got that error from the achievements mod.
I suggest taking out your addons you recently installed and see if it’s still there.

If it is:
Then clean gmod.

If it isn’t still there:
Those are the culprits.

i have the same thing but is says
…memodes\sandbox\entities\weapons\gmod_tool\stool.lua:92: attempt to index a nil value
