Hello, I follow the perfect server guide (debian 9) to install IspConfig. Everything works except phpmyadmin: missing mysqli extension. It's very strange because: >php -m | grep mysqli = mysqli > locate mysqli.so = /usr/lib/php/20151012/mysqli.so > phpinfo() addtional inifile: /etc/php/7.0/cgi/conf.d/20-mysqli.ini MysqlI Support: mysqlnd 5.0.12-dev - 20150407 - $Id: b5c5906d452ec590732a93b051f3827e02749b83 $ mysqlnd API Extensions: mysql module MySQLi I've another server, the only difference is php version (5.6 vs 7), where everything works. Do you have any suggest? I tried to remove and reinstall phpmyadmin, php, mariadb. Thank you EDIT: After 1 day, I found the solution. phpmyadmin was using php5 instead of php7. So: a2dismod php5 a2enmod php7.0
