I've correct DOCUMENT_ROOT as suggested but now i've no errors only a blank page
Try to analyze your logfiles:
/var/log/httpd/error_log and /var/log/httpd/access_log and perhaps also /var/log/messages.
Furthermore you should enable error logging and display errors on screen until you have succesfully finished installation.
This can be done like this:
mkdir -p /etc/e-smith/templates-custom/etc/php.ini
cp /etc/e-smith/templates/etc/php.ini/30ErrorHandling /etc/e-smith/templates-custom/etc/php.ini
After that:
cd /etc/e-smith/templates-custom/etc/php.ini
pico 30ErrorHandling
Modify the second line to read:
display_errors = On
After that issue the following commands:
expand-template /etc/php.ini
/etc/rc7.d/S86httpd-e-smith restart
Now access your page again and see what the error is.
If everything works you remove the 30ErrorHandling file from the /etc/e-smith/templates-custom/etc/php.ini folder and issue the last two lines again:
expand-template /etc/php.ini
/etc/rc7.d/S86httpd-e-smith restart
