I am getting this error on my Sandbox server. I completely reinstalled my server but I still get this error. I think it may be an addon.

[ERROR] gamemodes/sandbox/gamemode/cl_init.lua:86: attempt to call field 'PostRenderVGUI' (a nil value)
  1. old_hook_call - gamemodes/sandbox/gamemode/cl_init.lua:86
   2. unknown - lua/includes/modules/momo/compat.lua:23

Try verifying the integrity of the game cache on steam. just right click the game on the steam library menu>then press properties>the go to local files>then click verify the integrity of game cache. that will probably work.

  • I don't think it will work on a server. That is client side, it is server side. – Camouflaged Cow Aug 26 '16 at 19:39
  • oh I thought it was the whole game – captaincj2005 Aug 26 '16 at 21:46
