I think I have in this line the error, because in the error not say where is the error:

    void OnGUI() {
        GUILayout.Label( PhotonNetwork.connectionStateDetailed.ToString() );

        GUILayout.BeginArea (new Rect (0, 0, Screen.width, Screen.height));
        GUILayout.BeginHorizontal ();
        GUILayout.FlexibleSpace ();
        GUILayout.BeginVertical ();
        GUILayout.FlexibleSpace ();

        GUILayout.BeginHorizontal ();
        GUILayout.Label("Username: ");
        PhotonNetwork.player.name = GUILayout.TextField(PhotonNetwork.player.name);
        GUILayout.EndHorizontal ();


        if (PhotonNetwork.connected == false && connecting == false){
            if( GUILayout.Button("SinglePlayer") ) {
                connecting = true;
                PhotonNetwork.offlineMode = true;
                OnJoinedLobby();
            }
            if( GUILayout.Button("MultiPlayer") ) {
                connecting = true;
                Connect();
            }

Anyone help me please?!

You get that error when you do a begin horizontal/vertical/scrollview/group etc and dont have a matching End xxx
Although you DO have the End xxx in your script, they are wrapped in an if (), when the conditions dont match, the End xxx isnt called.

A half-hour bump isn’t called for
