PhotonView stating method doesn't have proper number of arguments.

I have many other [PunRPC] calls which work just fine. After modifying an existing call, it breaks. I'm not sure what's causing this. I went to the PhotonServerSettings and can see that RPC_AllPlayersInGameboard is in the Rpc list; I have tried clicking refresh.

I receive the following error:

method:

[PunRPC]
private void RPC_AllPlayersInGameboard(PhotonPlayer[] players)

caller:

photonView.RPC("RPC_AllPlayersInGameboard", PhotonTargets.All, PhotonNetwork.playerList);
