This will fix it to work on 4.1.2 like it did before. Replace the code in the forumhome_complete hook with the following:
Code:
if (THIS_SCRIPT == "index" and $vbulletin->options['ugcb_onoff'])
{
$activeusers2 = '';
$userbuls = split(',', $vbulletin->options['sirala']);
foreach($userbuls AS $userbul)
{
$activeusers2 .= $vbulletin->usergroupcache["$userbul"]['opentag'] . ' ? ' . $vbulletin->usergroupcache["$userbul"]['title'] . $vbulletin->usergroupcache["$userbul"]['closetag'] . ' ';
}
$vbphrase['most_users_ever_online_was_x_y_at_z'] .= '<p><b>'.$activeusers2.'</b></p>';
}
I expect to see lots of Boofo donations for this.
