Web-MeetMe Requesting Multiple Logins on 2.8.0.4 - Not Displaying Data

On an installation of 2.8.0.4, repeated logins are being requested, and the "logged in" user (an admin) cannot see any conferences, change conferences, etc. The only data being shown is in the reports section (number of conferences graph). Conferences can be scheduled with the web interface and will show in MySQL (with a select * from booking;), but they cannot be seen from Delete / Past / Current / Future Conferences. Users are not showing up in the Update user section either. Finally, calling the custom destination and putting in an active conference number will give an "invalid conference number" message.

This happens on an out of box install on 2.8.0.4, which shows a version of 3.0.4-37 in the packages section. On 2.8.0.3, which also shows a version of 3.0.4-37, it works without problems. I've also attempted to install Web-MeetMe 4.0.2 with the same problems on 2.8.0.4.

On both 2.8.0.4 and 2.8.0.3, a number of errors are showing in the /var/log/httpd/error_log, most of which are common between versions. The unique error for 2.8.0.4 is:
PHP Notice: session_start() [function.session-start]: Server localhost (tcp 11211) failed with: Connection refused (111) in /var/www/html/web-meetme/meetme_control.php on line 27, referer: http://10.21.4.42/web-meetme/meetme_control.php?s=2&t=4

A comparison of the two machines is virtually identical, outside of the kernel and Asterisk version:
2.8.0.4:

A diff of php.ini, httpd.conf, my.cnf, /etc/trixbox/httpdconf/trixbox.conf, and /etc/httpd/conf.d files between 2.8.0.4 and 2.8.0.3 shows no differences. The files in /etc/php.d are the same between trixbox versions.

On both trixbox versions, I have verified MySQL access with "mysql -u root -p(password from database.php)".

I have also attempted to remove and re-install the module on 2.8.0.4, remove the /var/www/html/web-meetme folder and replace it with the one from 2.8.0.3 (verifying identical permissions) and dropping the db and replacing it with the 2.8.0.3 meetme db.

Any help would be greatly appreciated. database.php and defines.php below.

database.php:
<?php
include_once 'DB.php';
$database = 'meetme';
$host = 'localhost';
$username = 'root';
$password = 'passw0rd';
$dsn = "mysql://$username:$password@$host/$database";
$db = DB::connect($dsn);
if (DB::isError($db))
{
die ($db->getMessage());
}
?>
