Can't log after uprade to 3.2 version

I have upgraded again to v3.2.0 (overriding the Apache folder with 3.2.0 version).

After that it shows 17 errors during database update, but I have checked the log file and it is due to already existing items.

When I try to log in with Javascrypt console open (in the server), it shows the next errors:

POST http://localhost/proyectos/tool/loginCheck.php?destinationWidth=350 500 (Internal Server Error) dojo.js:15
Error en xhrPost el retorno para loadContent('../tool/loginCheck.php?destinationWidth=350', 'loginResultDiv', 'loginForm', 'undefined') : <br/> RequestError: Unable to load ../tool/loginCheck.php?destinationWidth=350 status: 500 projector.js:628

Yes, with the next text:

<?php
$parametersLocation = 'D:\FicherosApacheProyectos\Config\parameters.php';

Yes, that file exits, with the next text:

?php

$logLevel='3';
//======= END

The root directory of the App has full rights to these users/groups:

Administrators Group
Creator Owner
System
Everybody

So, I don't think is a problem of rights...

Another idea?
