Problem with application

[eluser]1234qwer[/eluser]
Hello

We have developed a big real estate site on our localhost ussing php5 (and everything is well here), now we just upload it to the server (php4 by defautl but changing the .htaccess they provide php5 -we test it with a simple function only for php5-) and nothing... all displayed is a white page, no error, no problem, no warnings, we modify the .htaccess like the following:

Code:

Options +FollowSymlinks
RewriteEngine on

addtype application/x-httpd-php5 .html .htm
AddType application/x-httpd-php5 .php
AddHandler application/x-httpd-php5 .php

Rewritecond %{REQUEST_FILENAME} !-f
RewriteRule \.php$ /error404.html


RewriteBase /

RewriteCond $1 !^(\/|index\.php|system|_common|application|greybox|mod_galeria|basura|temp_img|support|mod_bienes_raices|blog|mod_css|mod_img|mod_scripts|includes|adm_img|adm_css|resize|views|templates|img|js|css|images|tester|system\/plugins|robots\.txt|language|css\/)

RewriteRule ^(.*)$ http://www.site.com/dir/index.php/pz/index/$1 [L]

and we add a file called php.ini on the folder where the script is with the following:

cgi.fix_pathinfo = 0;


We can figure out where is the problem, please give us some light.

Thanks.
