What do you mean "other player are admins". If you're saying that other people can execute administrative commands, then it's your code.

Place this code within you script, create a new account and test it.

PHP Code:

YCMD:test(playerid, params[], help)
{
    #pragma unused help
    #pragma unused test
    if(PlayerInfo[playerid][pAdmin] < 1) return SendClientMessage(playerid, -1, "You are not an Admin!");
    SendClientMessage(playerid, -1, "You are indeed an Admin!");
    return 1;
}
