I saw the mistake, you forgot 1 index of the array (playerid in the check if "playerid" is leader)

The array is fine!
Here you are the fixed CMDs:

PHP код:

CMD:setmafialeader(playerid,params[])
{
    new mafiaLevel;
    new mafiaID;
    if(IsPlayerAdmin(playerid))
    {
    if(sscanf(params,"ui", mafiaID, mafiaLevel)) return SendClientMessage(playerid,COLOR_RED,"USAGE: /setmafialeader [ID] [0-1]");
        mafiaInfo[mafiaID][MafiaLeaderID] = mafiaLevel;
        SendClientMessage(playerid,COLOR_WHITE, "{FF8200}Information:{FFFFFF} You have been set as leader of the Mafia.");
    }
    else
    {
        SendClientMessage(playerid,COLOR_RED, "ERROR: You are not allowd to use this command!");
    }
    return 1;
}
CMD:mafiainvite(playerid, params[])
{
    if(mafiaInfo[playerid][MafiaLeaderID] >= 1)
    {
        new mmemberID;
        if(sscanf(params,"i", mmemberID)) return SendClientMessage(playerid,COLOR_RED,"USAGE: /minvite [ID]");
        mafiaInfo[mmemberID][MafiaMembers] = 1;
        SendClientMessage(playerid,COLOR_ORANGE,"Information:{FFFFFF} Player has been invited!");
        SendClientMessage(mmemberID,COLOR_ORANGE,"Information:{FFFFFF} You have joined the Mafia.");
    }
    else
    {
        SendClientMessage(playerid,COLOR_RED, "ERROR: You are not the Mafia Leader!");
    }
    return 1;
}
CMD:mafiakick(playerid, params[])
{
    if(mafiaInfo[playerid][MafiaLeaderID] >= 1)
    {
        new mkickoutID;
        if(sscanf(params,"i", mkickoutID)) return SendClientMessage(playerid,COLOR_RED,"USAGE: /mafiakick [ID]");
        mafiaInfo[mkickoutID][MafiaNONE] = 1;
        SendClientMessage(playerid,COLOR_ORANGE,"Information:{FFFFFF} Player has been kicked out!");
        SendClientMessage(mkickoutID,COLOR_ORANGE,"Information:{FFFFFF} You have been kicked out of the Mafia!");
    }
    else
    {
        SendClientMessage(playerid,COLOR_RED, "ERROR: You are not the Mafia Leader!");
    }
    return 1;
}
