OK, so I installed mailcow on my test server and can see what I <should> be seeing, so now the question is this: is there a way I can re-install the GUI on a live (almost-functioning server) without breaking anything?
I created a tar file of the ./data/web/ directory on the “new/good” working server and extracted on the broken one, but then SoGo and Roundcube failed to connect to the mail database. (I suspect there’s a config file or two that got overwritten.)
What’s the best way to approach this without doing a full re-build? Any ideas?
