Installation problems with 2.3 versus 2.2.3

I am trying to install WordPress 2.3 on a subdomain of my server but I have problems related with the openbase_dir. However, the same server settings not have problems with the 2.2.3 version. Here it is both installation install.php URL:

– WordPress 2.3: https://magazine.art-signal.com/wp23/wp/wp-admin/install.php
– WordPress 2.2.3: https://magazine.art-signal.com/wp223/wp/wp-admin/install.php

The second one works but the first have errors. I can give more details about my server from WP-ServerInfo plugin like this:
