Well its because TheInnocentOne forgot to return 1;
add a return 1;

EDIT : Here :

pawn Код:

new god[MAX_PLAYERS]; // On top

public OnPlayerConnect(playerid)
{
  god[playerid] = 0;
  return 1;
}

public OnPlayerCommandText(playerid, cmdtext[])
{
  if(strcmp(cmdtext, "/gods", true) == 0)
  {
        if(IsPlayerAdmin(playerid))
        {
            if(god[playerid] == 0)
            {
            god[playerid] = 1;
            SendClientMessage(playerid, COLOR_MAGENTA, "GODSMODE ON");
            SetPlayerArmour(playerid, INFINITY);
            SetPlayerHealth(playerid, INFINITY);
            }
           
            if(god[playerid] == 1)
            {
            god[playerid] = 0;
            SetPlayerHealth(playerid, 100);
            SetPlayerArmour(playerid, 100);
            SendClientMessage(playerid, COLOR_MAGENTA, "GODSMODE OFF");
            }
        }
    return 1;
    }
    return 0;
}

Also, I would recommend you to use dcmd :P
its easier + faster
