Does anyone know what might be causing a "500 Internal Server Error" when I try to access the Parallels Infrastructure Manager Web Interface? A few hours ago when I logged in it was working OK and I have made no changes at all. All I did was to restart a container and log out. Which log files should I look to? Can I restart the Web Interface somehow and not the whole server? I have installed Parllels Infrastucture Manager 4.0 on CentOS 5.2.
