I usually make a strong mental note to init variables, but in this case it doesn't really matter as vBulletin generates around 20 notices per page, and unlike other scenarios - this wouldn't affect functionality. If you want to "fix" it, just edit the "Support Forum - Sort By Open" plugin: find

PHP Code:

if (in_array($foruminfo['forumid'], $checkForums) and strpos($sqlsortfield, 'lastpost') !== false)
{
    $sqlsortfield = "thread.open desc, $sqlsortfield";
    $hook_query_where .= ' and thread.open <> 10';
    $vbulletin->options['openAtTop'] = true;
} 


, below it add

PHP Code:

else
{
    $vbulletin->options['openAtTop'] = false;
}

$openThread = 0;
$closedThreads = 0;
$lastOpenStatus = 'zz';
