Hi Guys, Debian 9, with all updates installed. I get this error on trying to update ispconfig: root@zack:/tmp/ispconfig3_install/install# php -q update.php >> Update Operating System: Debian 9.0 (Stretch) or compatible This application will update ISPConfig 3 on your server. Shall the script create a ISPConfig backup in /var/backup/ now? (yes,no) [yes]: Creating backup of "/usr/local/ispconfig" directory... Creating backup of "/etc" directory... PHP Fatal error: Uncaught Error: Call to undefined function mysqli_connect() in /tmp/ispconfig3_install/install/update.php:234 Stack trace: #0 {main} thrown in /tmp/ispconfig3_install/install/update.php on line 234 Recommendation on how to fix?
There is PHP module not installed. Somehow you missed those when setting up ISPConfig. You have to install the php-mysql and php-mysqli extensions from your linux distribution.
