I followed the setup ISP-Server Setup - Ubuntu 5.10 "Breezy Badger", The problem i have is that phpmysql is not running, when i do the command php-m, phpmysql is not in the list. I didn't comment out de php things, because i don't setup ispconfig. I tried the solutions mentioned below. 1. Reinstal php4-mysql by running: apt-get install php4-mysql root@drbyte:apt-get install php4-mysql Reading package lists... Done Building dependency tree... Done php4-mysql is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. 2. Uncommented the line in php.ine wich reads mysql.so /etc/init.dapache2 restart, still no phpmysql running. I also searched the internet for a week of 2 now, but still haven't found a solution for this. I found that there a lot of pepople who have also this problem. When i run a php script in a terminal wich connects to a mysql database i get the following error. Fatal error: Call to undefined function mysql_select_db() in /var/www/usnet/inc/optimize_database_2.php on line 8 I hope to find a solution with help from this forum.
