pawn Код:

{
return IRC_Say(IRC_EchoConnection[0],channel,"4Invalid.");

must be

pawn Код:

}
return IRC_Say(IRC_EchoConnection[0],channel,"4Invalid.");

Thanks to realcop.
So this wuold be the complete code:

pawn Код:

IRCCMD:explode(botid, channel[], user[], host[], params[])
{
    if(IRC_IsOp(botid,channel,user))
    {
        GetPlayerName(playerid, sendername, sizeof(sendername));
        giveplayerid = strval(tmp);
        GetPlayerName(giveplayerid, giveplayer, sizeof(giveplayer));
        GetPlayerName(playerid, sendername, sizeof(sendername));
                if(IsPlayerConnected(giveplayerid))
                {
                    format(string, sizeof(string), "You exploded %s",giveplayer);
                    SendClientMessage(playerid,COLOR_RED,string);
                    SetPlayerHealth(giveplayerid, 10);
                    new Float:boomx, Float:boomy, Float:boomz;
                    GetPlayerPos(giveplayerid,boomx, boomy, boomz);
                    CreateExplosion(boomx, boomy , boomz, 7, 10);
                    new msg[128];
                    format(msg,sizeof(msg),"0,4Admin %s has exploded %s (type 7 explosion)", nameee, giveplayer);
                    IRC_GroupSay(IRC_Group, EchoChan, msg);
                    IRC_GroupSay(IRC_Group,"PRIVATE CHAN",msg);

                    GetPlayerName(playerid, nameee, 30);
                    printf("[Command] %s has used /explode to explode %s", nameee, giveplayer);
                }
                else
                {
                    format(string, sizeof(string), "%d is not an active player.", giveplayerid);
                    IRC_GroupSay(IRC_Group, EchoChan, msg);
                }
        }
        return IRC_Say(IRC_EchoConnection[0],channel,"4Invalid.");
    }
    return 1;
}

If realcop didn't say that, I wouldn't see it
