Hello everyone, I have a problem, I have installed ISPConfig on my Debian 10 server and together I have installed Roundcube, the problem is that when I look for server / webmail address it returns this error "DATABASE ERROR: CONNECTION FAILED! Unable to connect to the database ! Please contact your server-administrator ". I saw from phpMyAdmin that the database is there but it is empty and there is also the roundcube user on MySQL. Thanks to those who can give me a hand to solve this problem.
