I am getting this error in roundcube after install through virtualmin script.Any help pls.
You need to make sure that the database password is set and Webmin/Server MySQL Database Server module can connect to MariaDB server (I suppose you are using Debian 10). There was a patch to address password change in later versions of MariaDB, which you can easily apply by replacing feature-mysql.pl file, and restart Webmin.
Thanks for your reply.
Currently I am using Ubuntu 20.04 lts development. but also same problem in 18.04 lts. How to replace feature-mysql.pl, file location? My database password i set when Post-Installation Wizard is different from when i create virtual server password.
