Can't log into root user after Configuration of Web Server by Web deployment

Hello, I followed every steps from manual till mail server part:

Now my interface shows up but whenever I log in, It keeps up giving error such:

The page isn’t redirecting properly
** Firefox has detected that the server is redirecting the request for this address in a way that will never complete.**
** This problem can sometimes be caused by disabling or refusing to accept cookies.**

So now I truly don’t know why I am stuck here, even though I deleted or managed all the cookies on Firefox…
My RT config looks like that :

Set($rtname, '');
Set($Organization, '');
Set($WebDomain, 'localhost');
Set($WebPort, '80');
Set($WebPath, '/');
Set($WebImagesURL, $WebPath . "/NoAuth/images/");
Set($Timezone , ‘US/Central’);
Set($WebBaseURL , “http://”);
Set($DatabaseUser, 'rt_user');
Set($DatabasePassword, 'nabersin');
Set($DatabaseHost, 'localhost');
Set($DatabaseName, 'rt5');
Set($DatabaseAdmin, 'postgres');
Set($LogToSyslog, 'info');
Set($LogToSTDERR, 'warning');
Set(%GnuPG, 'Enable' => '0');
Set(%SMIME, 'Enable' => '0');

Whereas VirtualHost looks like that:

    <VirtualHost *:80>
        ### Optional apache logs for RT
        # Ensure that your log rotation scripts know about these files
        ErrorLog /opt/rt5/var/log/apache2.error
        TransferLog /opt/rt5/var/log/apache2.access
        LogLevel debug

        AddDefaultCharset UTF-8

        # SCRIPT_NAME should match RT's WebPath, without a trailing slash.
        # This means when WebPath is /, it's the empty string "".
        ProxyFCGISetEnvIf true SCRIPT_NAME ""
        SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=$1

        # The location path in the first argument should match the WebPath in your
        # RT site configuriation.  The network location after fcgi:// should match
        # the ListenStream in rt-server.socket.
        ProxyPass / fcgi://localhost:5000/

        ScriptAlias / /opt/rt5/sbin/rt-server.fcgi/

        DocumentRoot "/var/www/share/html"
        <Location />
            Require all granted
            Options +ExecCGI
            AddHandler fcgid-script fcgi

Thanks in advance for response.
