I have tried letoDMS-3.4.0RC4, letoDMS-3.4.0RC5 & letoDMS-3.4.0RC6 and also some other old version but I am struck with blank screen during the installation of install/install.php script, I am using

# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5.7 (Tikanga)
# php -v
PHP 5.3.3 (cli) (built: Jan 20 2011 06:13:52)

# httpd -v
Server version: Apache/2.2.3

[root@localhost resources]#

I have tried : adodb-ext-504.zip and adodb_lite1.42.zip

But no luck,

Any suggestion to complete the installation

Thanks
