Spawn list not showing

I dunno if there is a thread about this already, but im just full of this **** >:(

When i press Q i just get an error:

ERROR: GAMEMODE:‘OnSpawnMenuOpen’ Failed: sandbox\gamemode\spawnmenu/spawnmenu.lua:50: attempt to index global ‘g_ContextMenu’ (a nil value)

And nothing happens, i’ve tried everything, but it isnt working…

Sounds like it’s an addon conflicting with it. Try getting rid of your addons and see if it works, then maybe put addons back 1 by 1.

Nope. Didnt work… And this only happens in multiplayer, it works fine in singleplayer.
