Problem with game.Players.LocalPlayer, Help?

After the Maintenance. I opened up Roblox Studio to edit the scripts and some of my scripts aren't working? I fixed each of them and nothing works. It says an error that it is a nil value.

local bahhh = game:GetService("Players").LocalPlayer

This even don't work. I tried some replacements and nothing can fix it. I need help?

If you're running the code in a normal (server) script it's because the server have no player, and in turn there is no local player. It can only be used in local (client) scripts.
