I transferred a virtual server from one Virtualmin installation to another. The server appears to have transferred perfectly well, but the client wants to use RoundCube webmail. So I tried to install it and I got the following error message:
'This script cannot be installed, as this virtual server does not meet its requirements : A MySQL database is needed.'
So, I went to Webmin -> Servers -> MySQL Server and there seems to be a running version of MySQL. There are five tables: admin, performance_schema, information_schema, test and mysql. I accepted all the defaults and the domain worked with RoundCube before it was transferred.
Not sure where to start to try and make it work.
