I have IPSConfig3 running on a Debian 8.11 system. I updated ISPConfig a couple weeks ago and ran into some issues with some IMAP accounts I am hosting on the server, but I was able to fix that. However, when I try to log int to he control panel, I just get a blank white page and the following error in my Apache error.log file: Code: mod_fcgid: stderr: PHP Fatal error: Call to undefined function mysqli_init() in /usr/local/ispconfig/interface/lib/classes/db_mysql.inc.php on line 83 I have php5-mysql installed and have verified that the mysqli module is loaded by running: Code: php -r 'phpinfo();' | grep -i mysqli I have another ISPConifig3 server that I upgraded att he same time, and it is running fine, though it is on a Debian 10.1 server. I am not averse to doing a OS upgrade of the Debian 8 to 10, but there is no guarantee that will the issue, and I would rather fix it without going throught he upgrade if possible, since I plan on retiring this server soon. Any insight or suggestions appreciated. Thank!
