It appears the issue is caused by ibproarcades code.
I was able to fix this problem by editting the arcade.php and changing this
Code:
$vbversion = substr($vboptions[templateversion],0,3);
if ($vbversion != "3.0")
{
($hook = vBulletinHook::fetch_hook('ibproarcade_new_champ')) ? eval($hook) : false;
}
To this
Code:
// $vbversion = substr($vboptions[templateversion],0,3);
// if ($vbversion != "3.0")
// {
($hook = vBulletinHook::fetch_hook('ibproarcade_new_champ')) ? eval($hook) : false;
// }
The code was disabling the hook.
