auth problem on a new server

Hello, my problem is very ... i don't know a word. :-( System: Suse9.1 apache2-prefork-2.0.49-23 apache2-mod_php4-4.3.4-26 apache2-2.0.49-23 mysql 4.0.18 Fresh Pear-Istallation with lynx -source http://go-pear.org/ | php And now I wanted to rebuld the easy Auth example from the pear-documentation and nothing happens ... empty browser.

After searching in the auth.php I found the section with the     /**
     * Start new auth session
     *
     * @access public
     * @return void
     */
    function start()
    {

        $this->assignData();

        @session_start();

        if (!$this->checkAuth()) {
            $this->login();
        }
    }

I deleted the @ from @session_start(); and now I get this error : Fatal error: Call to undefined function: session_start() in /usr/share/php/Auth.php on line 267 Can anyone explain me this ??? session_start() is a normal command in PHP4 and now it could not be found ?? Is this a special Problem with apache2 ??? It is not the first time I use the auth.php. In older projects I used this class with apache 1 and mysql 3 without any problems. Only on the new server are these messages. Any ideas ? Thanks in advance. Regards -- Gunther Grelczak Deutsches Museum - Elektronik und Medien t: +49.89.2179-349 f: +49.89.2179-326
