Hi, I'm having a problem with FOP2 Manager. When I go to the login page it creates the tables and the admin user, but when I try to login it returns to the login page, it doesn't show the "invalid credentials" error so I think it's some other misconfiguration. Can you help me?

/var/www/html/fop2/admin/config.php:

<?php
define('USE_BACKEND_AUTH',false);
$ADMINUSER = "admin";
$ADMINPWD = "mypass";
$DBHOST="localhost";
$DBUSER="fop2";
$DBPASS="myotherpass";
$DBNAME="fop2";
$SQLITEDB="/usr/local/fop2/fop2settings.db";
$FORCE_UTF8=false;
$APPNAME = "FOP2 Manager";
$LOGONAME = "<span style='font-weight:bold; color:#000;'>FOP2</span> <span style='color:#4EB855'>Manager</span>";
$LOGO = "images/fop2managerlogo.png";
$DEBUG = 0;
$BUTTONS_PER_PAGE = 150;
foreach(glob('/etc/fop2/config-webadmin-*.conf') as $conf_file) {
include_once($conf_file);
}
