DarkRP serious error

Hey everyone i installed a few things on my server today but then when i went too test it out the f4 menu appears blank and in the console it says
DarkRP\gamemode\showteamtabs.lua:554: attempt to get length of global ‘CustomVehicles’ (a nil value)

what is causing this?


also heres the line of 554 in showteamtabs.lua
if #CustomVehicles <= 0 then return end

I have the same problem, any solutions?
