Hi Alan, thanks for your idea. I tried it but it didn't work.
The code I used was: <?php echo extension_loaded("mysql"); echo phpinfo(); ?> I get the following output from that script: Fatal error: Call to undefined function: extension_loaded() in /var/www/links/content/test.php on line 2 I also checked the phpinfo() output, the mod_php4 module for Apache is loaded and other scripts are working. These are the dselect selections for my PHP installation: *** Opt web php4 4.0b3-6 4.0b3-6 A server-side, HTML-embed *** Opt web php4-gd 4.0b3-6 4.0b3-6 GD module for php4 *** Opt web php4-imap 4.0b3-6 4.0b3-6 IMAP module for php4 *** Opt web php4-mysql 4.0b3-6 4.0b3-6 MySQL module for php4 *** Opt web php4-xml 4.0b3-6 4.0b3-6 XML module for php4 Did I forget a package? Thanks for your help. Bye, Sven
