I can't open C++ project on Unreal Engine 4.14

It says what the problem is right there in the log:

Basically, you reference AGameModeBase::SetPause, but the linker cannot find the implementation for it.
There are two possible cases:

1. You called it somewhere: remove or substitute that call to see if that solves the problem
2. You created a child class from AGameModeBase which is missing the SetPause function. Go and implement it in your class.

I just created the A C++ Class for Game Mode Base and got this error while it was being created. Is this a bug in the latest unreal version. (Mine is 4.14.3).

GameModeBase.h

virtual bool SetPause(APlayerController* PC, FCanUnpause CanUnpauseDelegate = FCanUnpause());

GameModeBase.cpp

bool AGameModeBase::SetPause(APlayerController* PC, FCanUnpause CanUnpauseDelegate /*= FCanUnpause()*/)
{
	if (AllowPausing(PC))
	{
		// Add it for querying
		Pausers.Add(CanUnpauseDelegate);

		// Let the first one in "own" the pause state
		AWorldSettings * WorldSettings = GetWorldSettings();
		if (WorldSettings->Pauser == nullptr)
		{
			WorldSettings->Pauser = PC->PlayerState;
		}
		return true;
	}
	return false;
}
