[Dadoo]

there is a BUG in txt file at

$Champion['ArcadeChampion1'] = "{$ibforums->lang['top3box_norank']}";
  $Champion['ArcadeChampion2'] = "{$ibforums->lang['top3box_norank']}";
  $Champion['ArcadeChampion3'] = "{$ibforums->lang['top3box_norank']}";
  $Cpt = 0;
$DB->query("select champ_mid, champ_name, count(*) nb, active, champ_gid, gid from ibf_games_champs inner join ibf_games_list on champ_gid=gid where active =1 group by champ_mid, champ_name order by 3 desc, 1 limit 10");
  while ($res = $DB->fetch_row())
  {
	$Cpt++;
	$Champion['ArcadeChampion'.$Cpt] = '<span style="font-weight: bold;"><a href="'.$ibforums->base_url.'act=Arcade&module=report&user='.$res['champ_mid'].'">'.$res['champ_name'].'</a></span><br />'.$ibforums->lang[top10_txt1].'<b>'.$res['nb'].'</b>'.$ibforums->lang[top10_txt2];
	$Champion['ArcadeChampionMid'.$Cpt] = $res['champ_mid'];
}

last "}" is missing..

otherwise, in first file edit (skin_Arcade.php) if you have make choice to have V3arcade skin and not ibProArcade skin, modify skin_v3Arcade.php file and not skin_arcade.php
