I'm wondering if anyone has a solution for this problem: Earlier today I was mucking around with Rails and needed to edit a vhost. Instead of using Virtualmin's 'Edit Directives' feature, I went directly to and did
$ sudo nano /etc/apache2/sites-available/vhost.
I didn't end up saving my changes (I realized I should just do it in Virtualmin) but I did notice that the Services -> Configure Website module was no longer functional. I was able to edit the same data on the Webmin end, in the respective module, but still 'Configure Website' is broken on Virtualmin's end.
Was there something overwritten by nano that might have caused this?
