I don’t know how or why, but VirtualMin has gone away on my server.
Please look at the picture below:
How can I fix this problem? Any ideas? I tried with different theme, but theme is not the problem.
Did you, by any chance, uninstall postfix or tinker with the database that would have been installed?
This happened to me recently when I was setting up a new server and messing around with the modules and ended up breaking Virtualmin.
Eventually I found a thread about running the virtualmin readiness checker and I realised that postfix wasn’t installed and needed to be.
Anyway, there was a precursor to it stopping so I suspect that has happened here.
