Need help on my server.

Basically my server I run on steam CMD was working fine 2 days ago till now. It has script errors and cant open my Q or c menu or even my admin menu (using the latest evolve from github) My friend gave me his server files that are fully functional, so I basically swapped over to that and still no fix. And my console get spammed with many errors. If anyone could add me on Skype or maybe know a fix that would be great thanks.
p.s my server is fully updated.

Reinstall your server through SteamCMD.

Also, make sure it’s a serverside issue, not clientside.

Ok I will check that ty

Maybe you should post error, code where error located and skype login?

theres many errors but the recent one is when I added pointshop. [ERROR] addons/pointshop-master/lua/vgui/dpointshopmenu.lua:285: attempt to call global ‘Derma_DrawBackgroundBlur’ (a nil value)

  1. unknown - addons/pointshop-master/lua/vgui/dpointshopmenu.lua:285

Also on my custom start.bat when I run it it says Lua JIT is DISABLED! then
couldn’t find “lua/derma/derma/init.lua” <<nowhere>>

Reinstall your server; you’re missing a default file.
