install/index.php is blank or shows an error. Whats wrong?
This can have several reasons. • If the page is blank and you’re using PHP 5.0.5, then you need to change the PHP version. See PHP bug 34635 • If you get something like “Warning: session_start():”… then your PHP is misconfigured. You probably need to set session.save_path correctly (on linux / unix “session.save_path /tmp” is a good choice). And / or you need to configure the session.save_handler correctly (“session.save_handler files” is a good choice). These settings are in php.ini of your PHP installation and you need to restart the webserver after the changes. You may be able to set the necessary PHP session variables without altering your main php.ini file by placing configuration directives in your Gallery directory’s .htaccess file (Reference). • Else: Make sure you run PHP 4.1.0 or a newer version and make sure PHP is actually used for .php files on the webserver.
