You are missing IsPlayerConnected

PHP код:

#pragma unused params
if (IsPlayerConnected(playerid)) {
    for (new i = 0; i < MAX_PLAYERS; i++)
        if (IsPlayerConnected(i) && (PlayerInfo[i][pMember] == 1 || PlayerInfo[i][pLeader] == 1))
            LEOOnline++;
    
    if (LEOOnline < 4)
        return SendClientMessage(playerid, COLOR_GRAD3, "You need at least 4 Law Enforcement officers!");
}
