OK, that explains that discrepancy–the other two template fragments I’m seeing come from that, so if you don’t have it installed, you wouldn’t see them. But that leads to the question of why renaming the file had any effect for you. My hypothesis is that having the automx fragment before the default virtual host fragment resulted in the automx fragment becoming the default, as far as Apache is concerned (though I still can’t imagine how that would have effected the server manager). Renaming it from 05
to 15
put it after the default, and the Graphs page in my server manager now comes up just fine.
If you don’t have the web server module installed in the first place, there is no default virtual host, so I can’t see how the order of that file would affect you.
