OK.. there is a problem with Safari and their Cross-Origin Resource Sharing (CORS) implementation, which is causing Javascript errors when ads or videos are served.

This bug is causing an error in the Trivia JS code, so I have am disabling the trivia for guests (not logged in) who are using Safari (for now, in both mobile and desktop):

Code:
<?php
$user_agent = $_SERVER['HTTP_USER_AGENT'];
if ($vbulletin->userinfo['userid'] < '1') {
    if (stripos($user_agent, 'Chrome') !== false) {
        define('ENABLE_SAFARI_UA', true);
    } else {
        if (stripos($user_agent, 'Safari') !== false) {
            define('ENABLE_SAFARI_UA', false);
            $log = '/var/log/apache2/debug/neo_trivia_global_safari_debug.log';
            error_log(date(DATE_RFC822) . ' UA ' . $user_agent . "\n", 3, $log);
        } else {
            define('ENABLE_SAFARI_UA', true);
        }
    }
} else {
    define('ENABLE_SAFARI_UA', true);
}

I will think about another "fix" for this later.
