I can not install the program in Italian.
I'm doing some tests.
Now I installed the English version.

http://lomanuto.bsnewline.org/b2evolution/blogs/blog1.php

I have done so:

1 modified _locales.php
--------------------------------------------------------------------------
$locales['it-IT'] = array(
'name' => NT_('Italian (IT) latin1'),
'charset' => 'iso-8859-1',
'datefmt' => 'm/d/y',
'timefmt' => 'h:i:s a',
'startofweek' => 0,
'messages' => 'it_IT',
'enabled' => false, );

----------------------------------------------------------------------

$allow_po_extraction = 1;
------------------------------------------------------------------------
2 placed by the downloaded folder b2evo 1.8.xx taliano (it-IT) di _TeRmInEt_ - 2006/08/31
in folder "locales"
-----------------------------------------------
3 In the folder it-IT
I built (because it does not work!!) using a file-fr FR.locale.php
the new file saved as it-IT-locale.php was saved in the en-
obviously the file has been modified so

------------------------------------------
$locale_defs['it-IT'] = array(
'name' => NT_('Italian (IT) latin1'),
'messages' => 'it-IT',
'charset' => 'iso-8859-1',
'datefmt' => 'd.m.y',
'timefmt' => 'H:i:s',
'startofweek' => 1,
);
-----------------------------------------------------------------------
4 I also added in the folder "gettext/langfiles

il file it-IT.static.po

when I try to enable the language for this page::

http://lomanuto.bsnewline.org/b2evolution/blogs/install/index.php?action=localeinfo&locale=it-IT

The white page is not only recognized if I disable the varaibile da 1 a zero

$use_l10n = 0;

I can see the Italian flag, but of course nothing happens I tried a bit around

but nothing.

help
thanks Walter
