Have you changed the "params" thing for this line too? If you keep "params", it'll keep making error. Whole code should be like this:

pawn Код:

dcmd_ac(playerid,params[])
{
    new pname[MAX_PLAYER_NAME];
    new string[128], text[128];
    if(sscanf(params, "s[128]", text)) return SendClientMessage(playerid, -1, "USAGE: /ac [Message]");
    GetPlayerName(playerid, pname, MAX_PLAYER_NAME);
    for(new i=0; i<MAX_PLAYERS; i++)
    {
        if(AdminLevel[i] == 1)
        {
            format(string,sizeof string, "[ADMIN CHAT] %s(%d): %s", pname, playerid, text);
            SendClientMessage(i,COLOR_PINK,string);
        }
    }
    return 1;
}

Edited, use this last one.
